[He laughs a little, softly, privately-- he knows that, without Keith, he wouldn't even be here. It's because of Keith that he can feel so steady, that he can feel more accomplished in what they're doing. But maybe admitting as much would put too much pressure on him.]
[He tilts his head a little, looking at Keith with a soft look, his smile quiet but no less heartfelt.] Thank you, Keith. Being able to rely on you... you don't know what that means to me.
[He's quiet for a moment longer, just observing him for a quiet, comfortable moment.]
... Are you willing to tell me what brought all this on? [Why ask him all this? Yes, he noticed how you dodged that question before. Was he being sadder than usual? Or... For a panicked moment he fears this has something to do with almost kissing him in the boat fff did he push too far, or...] You don't have to, if you'd rather not.
