I'm sorry if this has already been said, but:

How did Dumbledore know that Voldemort had possesed Ginny, 
at then end of CoS... when Harry stopped talking because he 
didn't want to say that Ginny had done all the Petrifying? I'm pretty 
sure it was because of Occlumency, but if someone else has an 
idea, please tell me. 

Also, in PS/SS, when Hermione and Harry go up to the North 
Tower to drop off Norbert, and then leave the invisibility cloak, 
how did Dumbledore know where it was to return it to Harry's 
bed? Remember, it had a note attached to it that said: "Just in 
case." That was most likely Dumbledore who left it. How did he 
know it was there? Did he just find it there by accident and then 
return it to Harry?
