Because, Joker, one way or another he's sorry you feel that way, dammit. Unfortunately, though, it doesn't occur to him to actually explain his feelings on the subject. Instead, his ears give a confused flicker as he tries to process that answer.

On the bright side, he resists the impulse to make a crack about how Joker really must hate it here.

"It's not fair to you to cut yourself off from help." It's not hard for him to guess that Joker is talking about Psi, and he understands that hesitation - but.

"...I'm going to talk to Psi tonight." Just putting that out there. "And, Joker, I need you to understand - if he has a problem with me helping other people, that was going to be an issue one way or another, whether you told me what was going on or not."

He lets out a breath, tilting his face downward as he watches his own hooves. "...So I'm glad that you did tell me. So I... at least have the option of helping. And I want to take that option, whatever happens."

Now he hardly knows if he's making sense, and he's not even the drunk one.
