"Everything else is excluded." "(HUMMING)" "(MAN) Nothing." "Could they be shielded from the scanner in any way?" "A lead screen." "Some of the newer alloys." "There isn't anything like that in the cavern." " They're dead, aren't they?" " It does seem likely." " Such a pointless waste." " We'll find out." "They can't be far." "I radioed immediately I left the cavern." "You've done all you can." "Don't upset yourself." "Walters, scan again." "Maximum amplification." " How many of you were down there?" " Eight of us." " What were you doing?" " A survey." "The particular cave system we were in has just been discovered." "It's proven to be rich in fossils." " Are you all palaeontologists?" " And geologists." " It doesn't make sense." " Scan complete, sir." "Negative." "No sign of life." "(MAN) Right." "Get your gear together." "We're going down!" "I realise going down again must be hard." "The caves are uncharted." "You'll never find the bodies without my help." "I'm grateful!" "Snyder!" "I want you to stay here with Walters." " Sir." " Walters, I want a constant scan." "Let me know the instant you see anything, all right?" "(WOMAN) Troops ready, sir." "Sergeant Mitchell." "Do you believe Professor Kyle?" "I think she's telling the truth." " As far as she knows it, that is." " I agree." "All right." "Put the troop on full alert." "And just in case she is lying, we'll have her up front where we can see her." "They're making good progress." " Is that supposed to happen?" " What?" "It was a sort of flare." "It only lasted a second." "Probably nothing." "This equipment's ancient." " There!" " Ghosting." "Shouldn't we tell Lieutenant Scott?" "It isn't worth it." "You must read this, Adric. "The Black Orchid"." " Why?" " It's fascinating." "Such scholarship!" " Why should that interest me?" " What's the matter?" "I'm fed up." " Why?" " I'm tired of being considered a joke." " No one thinks that." " Then why am I constantly teased?" "Everyone's teased from time to time." " Yeah, but not as often as me." " That's not true!" "No, and I suppose neither is the fact that when Nyssa or Tegan ask a question, you find time to answer it, but hardly ever with me." "Doctor, how am I to learn if you never find time to explain?" "Time?" "We have spent many hours discussing and debating endless topics." "I'm just fitted in when it's convenient for you." " All right." "I'll make more time." " No." "You've said that before." "Some distraction always prevents it happening." "I give you my word." "Just as you gave your word to Tegan." " That's not fair." " I'm not allowed to criticise you, and it's never your fault when things go wrong." " Have you finished?" " There's more." " It can wait!" " I can't." "I'm tired of being an outsider, Doctor." "I want to go back to my own people." "(RUNNING WATER)" " Is this the only way down?" " The only known way." "It must have been fun getting the gear through there!" "We were cursed from the beginning." "Even lighting the tunnels was a nightmare." " In what way?" " All sorts of things." "Tools went missing." "Important components were discovered smashed." " Sabotage?" " I didn't think so at the time." "Someone who wanted to wreck the expedition could have been more determined." "As ultimately they were." " There." " I'll never be able to do that properly." "It isn't difficult." "(DOCTOR) I will not do it!" "The Tardis is not designed for E-Space!" "Tell him!" " Tell him what?" " He wants to go home." " To Alzarius?" " To Terradon." " That means going into E-Space." " It would be very dangerous." " I'd plot a course." " Using negative co-ordinates?" "I have the mathematical skill." "We'd have to pass through the CVE." "You can't calculate random co-ordinates!" "The monitor indicated they were not random." "You don't have the monitor's skill, and even if you did," " I am not going into E-Space!" " I'll find someone who will!" "E-Space is another universe." "There aren't taxis going back and forth!" "Once I calculate the course, the journey will be simple." " It won't." " Romana's still in E-Space." "Once I get there, she can help me." " Is it really that dangerous?" " Would I make this fuss if it weren't?" " Can I use your computer?" " Help yourself (!" ")" "I'm not waiting around while you plot your own destruction!" "(SCOTT) How much further?"

"I might be gone some time." "I'm going to talk some sense into the Doctor." "It's all getting rather silly, isn't it?" " I didn't mean to be so rude." " Why don't you calculate the course home?" "Show the Doctor it can be done." "When he's calmed down, we'll talk to him." " Will he listen?" " Of course he will." "This is the main group." "This is the wounded party." " Where have they come from?" " I don't know." "We have three unidentified life forms on the scanner." " One of the readings is ectopic." " (SCOTT) What does that mean?" "That one of the life forms has two hearts." "It's so peaceful and cool down here." "Breathe deeply and relax." "Now, go and make it up with Adric." "Please?" "All right, but I'm not taking him back into E-Space, and that's my final word on the matter!" "Look at his calculations." "It may be possible."

" Why?" " They may need help." " I'll let them know you're coming." "(DOCTOR) Fascinating." "(NYSSA) They're huge!" "Which creature had such bones?" " Dinosaurs." " An amazing species." " Are they your ancestors?" " I hope not!" " You should be proud if they were." " They had a brain the size of a pea!" "They were the most successful creature on the Earth." "Fossilised remains are all over the planet." "Not bad adaptation for a creature with a brain the size of a pea!" " How long did they exist?" " 100 million years or so." "They seemed so secure, yet died out virtually overnight." "Come on, Professor!" "It's like a graveyard." "How could such a successful species die out so quickly?" "Hypothermia, then starvation." " Caused by what, an ice age?" " Something equally as devastating." " The Earth collided with something." " An asteroid?" "Could be, I don't know." "I've always meant to slip back and find out." " Snyder." " You should be near the wounded party." "I can't see anyone." "They're on your level, about 30 metres away." "Advancing now." "Will leave communicator on." "(BANE) Is that you, Snyder?" "Are you sure they're on this level?" "Positive!" "They should be very close." "Hang on..." "The scanner's flaring." "The flaring's very heavy." "(SNYDER) See if you can get a fix on it."

"It was gigantic." "How could one asteroid wipe out all the dinosaurs?" "You're forgetting displacement." "Millions of tons of earth and rock would have been hurled up into the atmosphere, enveloping the whole planet." "Would it have blocked out the sun?" "Yes."
