That request is one he responds to readily enough.

I want you to hold me.

It's something he'd like right now, actually, not just waiting for that nebulous, hypothetical day when he will suddenly be well, uncursed and unburdened.

We could explore the ocean a bit. Just near the islands, but that's... quite far for me. I could work on an enchantment to allow me to breathe beneath the depths. With you, I believe I would be safe.

Oh, but that monster that attacked him is down there now. On the other hand, it didn't seem to be able to swim, so...

I don't know if I could learn to swim, but when I am with you, there is no need.
