There were some more snippets from the Spidey episode today in one of the Marvel Universe interstitial's. There was Spidey holding a ceiling from caving in because of some civilians while Cap was pummeling some member of (I think) the Serpent Society. Another shot of Cap telling Spidey something. Seems like it may be mostly a Spidey/Cap team up.
"So you don't like names, huh? Well, that's too bad, Frog-Face. 'Cause to me, you're nothing but a two-bit, no-account, second-rate, sewer-breath-baboon, with a brain of a pigeon and the face of an eel!"
