Pete back in Smallville

Ok, I guess it was nice seeing Pete back on Smallville, but I think I saw this "new" episode already. Pete acting impulsively, mad at Clark. Kara has now become Lana, mad at Clark, not tusting him, moving in with Lex. Seriously I think they just copied an pasted previous episodes to make one so called "new" one. These writer should have been fired during the strike. There's absolutely no creativity.
