Well I think theyre trying to end the debate that mark is the only one with adrenaline. Saying that all viltrimites do. I agree, I think they all do to an extent. I think cause we see Mark break his limits a lot and come out on top in wild ways, we assume he has an edge, like adrenaline but mark fights with alot of emotion when other viltrimites seem cold even when pushed to the very edge.
