Asclepios or Hygeia fits doc as well a Hippocrates and there are tons of nigh-invulnerable Greek heroes besides Achilles, he may seem a clear choice but someone who got Hercules or Perseus and was NK proof would hardly be a weird match. As I said, I don't believe anyone has a role to character match that is absurdly unique and at most they might just think it has because they're inside the proverbial box, name me a role and I'm sure I can list of several legit matches, or as legit as any other barring possibly those whose name is literally synonymous with something like Narcissistic. Remember that a doc need not be an actual medical expert, it could as easily be someone who has the the Bowl of Hygeia recovered from some adventure, or someone who got a bottle of water from some miracle fountain, or merely someone who is known to be a great bodyguard or protector, I'm less worried about someone exposing themselves as a power role then I am of them not realizing their are a bunch of other people who could fit the bill. What I really want to know is if people feel their is a legit connection between their character and their role, as opposed to their flavor explaining their role, and as revealing as that could be, we might be able to put a protection on that by asking vanillas to 'flip a coin' for yes or no, because in current context I'm mostly concerned with our one notable item, Beet's gender. I'm not positive how to safely explore this line of questioning but I think doing so is likely to be necessary and sooner than later.

One alternative question, which we may wish to ponder less for its immediate use but for future verification, is to pin people down on approximate time line or era, I actually think this might help us a lot.

So possibly alternative questions:

1) Do you feel your role power is more character or flavor based? Vanilla flip a coin.

[so if you felt your role was pretty obvious to your character, like bulletproof for achilles or doc for Hippocrates, character based, if the favor had been the primary basis for the power, like you've been told your dad was killed by one of the group and you're vig/SK over it, or you're role power was clearly explained by the flavor not the character's mythological expertise/ability, answer flavor, vanilla, flip a coin]

2) Which era are you from?

[We could break this easily into Dark Ages, Archaic, Classic, and Hellenistic eras, and if they spread is fairly uneven break them into smaller periods like pre/post Troy etc where anyone who was right during the big event could pick either]
