Looked like Boomerang to me
Personally I won't complain until Ultimate Spiderman really turned into Ultimate Team Ups.
The Wolverine-team up sounds pretty lame, I got to admit that. (At least with the recent Blockbuster arc in mind)
But I'm really looking forward to the Spiderman-Torch issues. For once, this is the first true interaction between any member of the UFF (which started out great but still lack in characterization) any any other ultimate character. Secondly, Spiderman and the Torch have had (I heard) great interaction in 616-universe. I'd like to see them two interact in Ultimate as well. (A lot more than spiderman and Wolverine, at least)
Dr. Strange, Electra and the Punisher don't count as team-ups in my opinion. Not more than Doc Connors, at least. Neither of them is a "hero" in his own right. Half of them are actually treated as "villains", just like Doc Ock or the Kingpin. As for Dr. Strange, I'm atually looking forward to some interesting interaction with Peter, possibly similar to Peter's present relation to Dr. Conners.
