Not some of y'all having the theory of the two facing the wall being Bakugou and Kirishima when they look nothing like them, maybe they facing the wall because Deku haven't developed their powers yet? But anyways with Shiggy I don't think Deku would kill him he might just do something else or Shiggy might destroy himself or AFO might, or someone else who knows just got to wait and see.
LETS GOOO SAVE EM ALLLL
