Wherever Zagreus is, there's a sleepy Thanatos nearby. He's not completely lost to the waking world, but his floating bobs up and down like he's at risk of falling asleep. He wants to help out with the recovery. He's in no condition to.

It's a little amusing that when an especially strong urge to pass out again comes, the first thing out of Thanatos's mouth is some version of "Hypnos, stop." Some habits are hard to break.
