No matter how badly written Disassembled was, Betsy was the one character that had the best showing in the entire event. And that's a lot to say about our girl!
Betsy was a prominent figure: she contributed to the team's decision-making, she had multiple power feats, she defeated multiple opponents mostly on her own, other characters depended on her and her powers, and she had a unique voice that wasn't interchangeable with other characters. Also, if it wasn't for her breaking Ororo out of Nate's control, Ororo wouldn't have attacked him and allowed the telepaths to break in.
Our girl is the true MVP.
