You can! Because you know what? If you don't, I'm gonna have to figure out a way to get you out! And it'll probably be stupid and dangerous and not all that moral! So don't make me do that!

[He'd do anything for Barry, no matter how stupid. And he knows Barry knows that. For example, how stupid an idea would reaching out be? Hal decides he doesn't care if it's stupid, reaching out just enough so Barry can feel his hand and know that he's there. Assuming Barry can feel anything at all right now]

You can do it. Or I'll drag your ass out if I have to. Whatever works.
