Jesse and Wells in “Unfinished Business”

Jesse

I'm the reason you killed that man. And that's a really heavy burden to bear.

Wells

I know. I know. I also know that what I've done, it's unforgivable. When your mother died, honey... something inside me broke. I couldn't protect her. And I... I swore... I swore on her grave, no less, that I would protect you, and then Zoom took you, and I snapped. I just snapped. I couldn't breathe, I... I couldn't lose the only other person that I love.
