You seem to be forgetting all the history that transpired between Scott and Stiles before this episode. Scott accused him of murder and basically said GTFO and turned to Theo.

Stiles also, when he attacked Scott, believed Theo to be responsible for his father's condition and, by extension, blamed Scott for trusting Theo in the first place.

I found his character choices to be a natural and expected progression from what has come before.
