I think the title explains this post. Who would like Prometheus to be? I don't believe he is just the son of a guy we never heard of until two weeks ago. I think the writers might still not have decided who they want him to be maybe they wanted him to be Malone but after most fans wanted Tommy they changed their minds but that sounds stupid and impossible.Anyway I would love it if Prometheus is Tommy I don't care if he isn't evil or that he is dead or that Colin O'Donnel might be busy because

1 and 2 Flashpoint or Lazarus Pit could easily change that  

3 Prometheus is masked another actor play him and they can use O'Donnel for the last two or three episodes after he is done filming Chicago Med.

Who do you want Prometheus to be Roy, Malone, Slade, hell even Eddie.
