What I want to know is how Kosh was able to find out about the Gregorian chant without getting out of his encounter suit. Vorlon telepathy? On that note, I hope he bothered to show this place to Lyta as well later; she could use some cheering up by perfect moments of beauty even more than Sheridan.

Re: Earth and Sheridan - I think what's his name from last episode who was after the doctor probably reported Sheridan was acting a bit fishy there. Plus you know, I wonder how much the generals were able to keep secret from Clark & Co. anyway given that Clark did have large parts of Psi Corps at his side.
