Yeah, I think I know who that mutual acquaintance is. Not a bad actor. I guess he got a bit type-cast in politician/government roles etc. But so did BC for a while, as the lone cranky genius. Yes, BC got more exposure & popularity than him after he landed the role in Sherlock. But still, is this enough to hold that amount of grudge? Sounds like there’s something else. But at the end of the day, what goes around comes around.
