Ten/Giles/Wesley fic, Part 1 of ?

Part 1 of my as-of-yet-untitled and incomplete Tenth Doctor/Giles/Wesley fic. Takes place during S3 BtVS for Giles and Wes, and after "Doomsday" for the Doctor. This part is PG-13. I plan for it to get R in later parts. Unbetaed and thrown out there. I'll probably edit and tidy it up for later distribution to communities. Here's what I've got so far.
