On topic of 'cheeriness' levels...Maria's very laid back as a character. She's not as super peppy and friendly as the inexperienced, new-girl Stealth Leader Amelia. So you've got a mix of different people to talk to in terms of the GM.

IDK what the offence team leader is like because he hasN'T PUT DOWN A PERSONALITY YET WE'RE WAITING HOVELMEIR NO RUSH

But you've got a cheery one, a laid-back one, and probably some sort of stern manly-man who oozes testosterone by the lorryload. Or a very gentle and kind butterfly. Who knows?
