Yeah, I wondered about that, too, but now I'm assuming that this is all part of his GRAND PLAN (he likes those; just like Cayden James) to get himself believably arrested, so that he can get into Slabside, so that he can use his wickedly supper strong smashy punches to kill Oliver Queen with his bare hands, and then escape via whatever root his plant, Stanley, has cooked up for him. Of course, Oliver will wipe the floor with him because Oliver can punch walls without drugs, thanks. Don't do drugs, kids.
I hope that the above is not the case, but fear that it may be so.
I liked this episode better than last week. Very nice to finally, finally see Diaz taken down. Glad Felicity got to face off against him. I would have liked a little more give from that scene. I know Diaz still has to bravado it, but some indication that he believed her for even a moment would have been great.
It was ugly to hear Dinah and Curtis complaining about losing credit to the Green Arrow "again." Even with all their stupidness last season, I didn't think they were mad that Oliver didn't share the credit. I thought they wanted to be a more equal part of the team (which was still stupid to me, but I could kind of understand it). This just makes them seem so small and horrible.
