(fic) Child's play- AC2/New Who Crossover Chapter 2

More crazy.  Hope this combination is appealing.  Feedback greatly appreciated.

Title: Child's Play
Fandoms: AC2/Doctor Who new series
Spoiler warning: AC2 finale/DW- S5 business
Other warnings: slash!  Shaun/Desmond, Ezio/Leonardo, crappy jokes
Rating:  R for current chapters/eventual NC 17
I do not own AC2 or DW.

Previous chapter is here. Needs to be read in order to make any sense. Might not make sense in any case.

( oh what have I done )
