I think it depends on the conversation. I mean, if they're trying to justify him? Most definitely. I know William gets livid when Wickham is brought up. In his William way where he gets very tense and doesn't talk and glares. But it's William level livid.
But if they're making sure you're okay because it's being brought up? Probably not such a good thing to be angry. I mean you're angry about him, but getting angry at people who just want to check on you? It makes things messy.
