Hmm, so now Harry's return and Dumbledore's interference have created another departure, the earlier return of Voldemort; I suspect this is going to cause interesting problems for Harry in more than one way. On the other hand, I wonder how long it's going to take Dumbledore to figure out just where he went wrong, if he'll ever admit that he did. I loved Crouch's actions and how Dumbledore is on the offensive. It should be interesting to see if Dumbles offers up Harry's 'kidnapping' in an effort to deflect interest from him and get Harry back (give you odds it doesn't work out as he expects at all).
It should be interesting to see how he next perturbs the timeline.
