Oh. I thought you had to steal it back because you need it to get the power.
If web's town and fully honest about his gem abilities, it's really easy to power him up. He can only trade once a day, but everyone can use an action to give. He can trade an emerald away and be given it back or trade back for it; whatever he has most recently gained is what he can use, until he has them all, then he's free use for all 7 plus unkillable, it's sweet.
It's believable to me, as powers, could have more, might not.
Nothing about what web says as he talks about his powers bugs me in itself. He feels honest, direct, interested, involved, sincere, practical. I get this, if he has to help himself, he needs perhaps more than 7 nights to get all the emeralds, and that's probably not going to happen, because some may be fake, there could be theft issues, he can't trade real emeralds away unless someone's kindly giving them back...
he needs our help to make his gem dreams come true, and with it, he could actually achieve full power N1. At that point it doesn't matter what order he got the gems in, he can just use them, and he's unkillable - but still presumably voteable. Who knows what actual powers he gets from the 6 unknowns, but he'd have 7 actions a night and any remaining fakes or whatever would be scooped up. And to make that happen, he 100% needs us to just give him emeralds, right now please. And he'll cooperate the heck about that, best as he can.
It's when he's talking about anything else. He's not interested in finding scum. He's interested in getting his emeralds, the right or all of them. Anyone anti-web needs to die if possible, and he's not any of those honest/direct/rest about anything else. He doesn't care. It's not interesting, important - and that seems to include if we lynch town or scum, long as it's not folks who would/could help him with what he actually cares about. But NJW, who can speed or slow his emerald gain and said would slow it unless/until web helps kill a scum - which I don't mind as a conditional - and sof and me, we're on his top kill list. His reads to me are way off.
My issue is I don't feel any of that focus and clarity and concern about anything but those emeralds.
And if he's town, I think he needs to also have a town win, as well as those emeralds, so I think he'd be interested and concerned about both. And I can't feel that. That's why I want him dead. But he actually feels fine to me when he talks about the emeralds. It's believable and consistent, it's literally everything else that doesn't add up.
