Eh, Storm claiming out of the blue isn't even something that surprises me anymore. I would've been more surprised if I came into the thread and saw that he hadn't claimed lol.
This being said, there's something about his claim this time around that concerns me. While his roleblocker claim last game was easy to believe because of the high likelihood that such a role exists and how fakeclaiming it would be practically suicide, Bomb is not nearly as common of a role, and would be easier to fake claim. I mean, I myself even fake claimed Vengeful last game (though I was town).
The main issue I have with this claim is how easy and relatively safe it is for Mafia to fake claim it. It would be really easy for scum to say they're the bomb, and then continuously hold on to that as the reason they survive every night. Easy win for Storm's scum team.
That said, I can't say where I stand regarding the legitimacy of the claim itself. On one hand, I can see Storm doing exactly what I said above and riding it out to the end as scum. On the other hand, he claims a lot and it's not out of character, and his claims are usually revealed to be true. The problem is, we can't risk the Vigilante kill on him, and cop investigations wouldn't mean much in case he's the Godfather. I certainly wouldn't make a claim like this as a goon, but as gf I would. In the long run, I think the safest thing for us to do would be to lynch him. Worst case scenario, he is the bomb and we don't lose an extremely useful role (his role is virtually useless now since Mafia will almost certainly focus on other night kill targets). Best case scenario, we lynch a mafia member early.
I'm going to place my vote on him for now for the reasons I outlined in the last paragraph. However, the day just began, so my vote may change if a better opportunity presents itself later.
Vote: Storm
Also, it was a really early claim, and some people have already pointed out the possibility of him trying to prevent anybody else from claiming. Having claimed townies in a game is bad for the mafia, so for Storm to claim early to prevent anymore claims would be rather smart. Overall, I think Storm would make for a very good day 1 lynch.
