Geten being a Todoroki also won't have sense since their ice quirk is that they create and project ice while Geten just manipulates it. So yeah, whether it's trolling or not I'm glad Hori went this way with Geten.
Besides Dabi we've still got Mr. Compress to delve deeper into. Which could be fun since he seems to be most classic old school style super villain of the bunch, in that he's clearly got a stage persona and outfit that's meant to match that persona rather than to be all that functional. We still don't know his back story or motivation. He is experienced and seems to be the most stable member of the group, but he tags along with them even in bad times so he's loyal. Writing this down I kinda really want to see what his deal is.
But yeah, I want some Dabi focus soon as well. Maybe not a full reveal, but just something more.
