I think Peter is behind Derek's loss of power. Derek is the most loyal and strongest of Scott's wolf friends and would present the biggest challenge to Peter if he tried to take the Alpha status away from Scott. Also, Derek was the only one able to defeat Peter when he was the Alpha. Removing Derek's powers gets him out of Peter's way, period. I do wonder if he is absorbing them somehow, tho. In the scene where he's shredding the Mute, Peter looked a lot stronger and more brutal than he's been in a long time.

We never found out what Peter was trying to learn from Talia's claws, but it looked like he was up to no good and he never wanted Derek around when he tried to use them. When he used Lydia to access them, I'm guessing he found a way to reverse the curse and used that against Derek.
