Cathode didn't immediately reply to Jenny, and had held her face downcast. She didn't have something to say that would help her, and didn't want to make the situation worse. Seeing her immediately jump into the first chance to be useful tho, gave her something to work with.
She pat her upper arm, saying "See, it's alright, we all have our bad moments, and you are already helping right now! ...w-well, about to! A-and the present is more important than the past!"
