I got the impression that Jason is actually talking to both of them. Helena is the one that fits the bat role, but Harvey also follows that motif.
I don't know if I've ever mentioned it here, but I've always been of the opinion that the heroes of No Man's Land are Babs and Helena
As much as I'd love to add Jim to the list, the fact remains that a) he compromised his own principles in taking Harvey's deal and b) his pride put an unnecessary wedge between the Blue Boys and the Bats for too long. Both were completely understandable, and the first kept the most orderly factions from targeting each other, but neither was among Jim's finest moments.
(It's an interesting quirk of the narrative that Jim finally decides to call Bruce on his shit at the time when he can least afford to. It's a completely logical character note, and a long time coming, and important to keeping the tension high from a meta perspective, but still...)
I'm awfully tempted to add Harvey to that list, for the reasons you list later on. I don't think that he's one of the heroes, but one can certainly make the case that he's the anti-hero.
