i lean more towards 'she's blinded' than not tbh. in the beginning of the quest topaz warns a npc to not call 'boss jade' or something like that, which implies that she Does know what pisses her off & has probably seen her get mad at her grunts. but i really don't think she's aware of the extent to manipulative jade is. otherwise jade would be comfortable to keep her around during the discussion w/ oti. she specifically says she didn't want topaz to see that side of her mentor - the manipulative, money hungry hustler side.

frankly, i don't think topaz is THAT naive as to not know what she does in the bonajade store because she Does know what jade's stone does afterall. but it's very likely she doesn't know how fucked up those contracts/wishes she makes with people are. aventurine probably does though.
