They've left him alone in his cell.
He can't really be said to be lucid but he has very acute instincts for when there's someone and when he's alone - it's the last of his senses to depart him - and he's alone.
And then suddenly he isn't.
The next day the kobolds go to visit the humans; Rána needs a break from the Quendi.
This is hard to communicate, of course, and Tirinquo is confused at the humans' mixed feelings.
Would one of the unhappy humans like them to hold their baby for them while they're here?
They haven't gone too far from the Quendi; Rána asks them to tell the humans that Tirinquo is familiar with babies and should be trustworthy, but if they'd rather not let them hold any babies today that's fine too.
She can also make them grow faster, depending on which ones they have... yeah, she can make those grow faster.
Tirinquo wanders off to watch the humans, keeping an eye on the one whose baby they have so they can return them when they wake up.
They grin and pat her arm sympathetically.
They'll hang out here, if that seems to be okay; they can watch the other humans just fine.
Tirinquo knows some things about getting babies to go to sleep, and gently gives her some pointers.
As soon as it becomes clear that this isn't appreciated, they stop.
They sit there for a little while longer and then wander off to see some more humans.
...stress plant or no, Tirinquo's not going swimming any time soon. They'll go hang out with the weaving humans and see if they can figure out any of the language.
