Buzz sees right through Sahira's ruse, briefly plays along with it anyway, drops the bomb on her that he knows, then just does what she wanted anyway. He knows he's awesome, as in his next appearance (as Sahira's boyfriend!), he's wearing a jacket that says C.M.O.A.

Even better is how Spinny was able to pull it off. Once again, as with her initial defeat of Evil Spinnerette, she was able to outwit him not only by using his own abilities against him, but by using what has proven time and again to be her real superpowers: her brains and quick wits. Remembering her talk with Greta prior to her encounter with him, she was able to deduce that his powers had distinct limits, primarily being the amount of glass shards that he is able to control at a given moment. With this in mind, she lures him into the campus greenhouse and chucks the CK Reactor (booby-trapped with a generous amount of C-4) out the roof, then webs up a makeshift shield for herself. The reactor blows, raining so many shards of glass down on the Colonel that he's unable to exert control over each individual shard, overloading his powers and causing him to get shredded to bits. Let's see him heal from that.
