It was a set up...they probably knew he was coming also I think Christoph is usin all his energy to not let Ryan read him and when he isn't around, he takes a time off to rest and regain energy.
You almost had me convinced. Until I saw this...

First of all they were EXPECTING Ryan?! What crap is he trying to pull now?! Also has anyone else noticed that Cristoph only sleeps when Ryan isn't there? Why doesn't he want to fall asleep around him?
