Context: X promised to do sth for Tom under a strict (and hardly feasible) condition. A and B comment on this very upset that Tom agreed. B says: "But he's Tom, he won't pick up the quarrel you're putting down".
The dialogue in question has been translated from Japanese.
I guess B means sth like "you know Tom, he's not a quarrelsome type" but perhaps I am missing sth?
