"As long as you're back in here and she's back in her communications room in, um... four minutes... and 32 seconds." "Ah." "Quite a work of art, isn't it, hm?" "But I suppose you'll prefer something a little less decorative." "Hm?" "Something more..." "coldly efficient." "(Sapphire) 'Are you through the door?" "'" "'Yes.'"

"(Market trader) 'Porkers here, one, seven... '" " You both came through there?" " (Sapphire) Yes." " What happened?" " Just look at this place." " I said, what happened?" " We got in." "There was a defensive time field, a sort of vacuum." " In that?" " Was it?" " This place is amazing." " Who set up this time field?" "Whoever made the capsule - a security device." " The time source wasn't involved?" " It had something to do with it." "Sensory control, all very sophisticated." " Don't touch anything." " Absolutely not." "This must be one hell of a communications room." " I said don't touch anything." " What is it, Steel?" "If that time source was involved with the defensive field..." " It's involved with everything." " It brought the capsules here." "It was instrumental in bringing them." "What would it have used to create that field?" "Space?" "No." "Uh, no." "Static space." "It could have left us out there in time and space." "Yes, it could have left us there indefinitely." "Why didn't it?" "It's been fighting us since we got here." " Why not this time?" " Then it would have the advantage." "Yes." " Do we go back the same way?" " (Silver) There's no other way." "Now, there's a comforting thought." "Sapphire?" "L-I don't quite understand, it hasn't been burned and it hasn't been cut." " What has happened to it?" " It's lost its..." "No, it's never achieved its molecular structure."

"someone did that?" "Yes." "And whoever it was... he was standing here, he was standing right here." "When?" "Not long before we arrived." "So where are they now?" "Somewhere." "We'd better locate it first." "Look, I get you in, I get you out." "I'm a technician, not an explorer." " You want to wait here?" " Alone?" " No." " Wait." "These are real, just like in the other capsule." "But this isn't." "No bricks, no plaster work..." " Is it the same as the outside wall?" " Yes, it's synthetic material." "What about the people?"

"What sort of signal would they need for that?" " Is it working now?" " No, it needs to be triggered." " I could get it to operate..." " I'm sure you could." " And cause panic in the process." " Panic?" "Back at base." "What's the first thing they might do if they heard strange voices?" "(Laughing) Yes, recall the capsule." " Could you get us off in time?" " No." "(Sapphire) Steel?"
