KIRA: Odo, are you here, Odo? I'm going to try to track down the source of the interference. If I can't find it and neutralise it, I'm going to have to leave here and try to find Sisko and the others. I'm really glad you made it home, Odo. I know everything is going to work out just fine. I don't believe it. I'm talking to a tree. You're probably not even here, are you?

KIRA: Why would shape-shifters need a door? Kira to computer. Scan the area dead ahead of me for one hundred metres.
