The hug was unexpected, but it can't be an instant fix because Ivan kept himself from crying for weeks now, he's used to being abandoned but to have to abandon what little he had to anchor him himself was so much worse. It does help in the long run, though, and Ivan's hand leaves the suitcase after a bit and fingers of both little hands curl into Timo's shirt, ruining it further as he presses his face into it. It's not that he trusts the stranger yet, but he wants him to stay, you have to stay, don't leave me alone, being alone is scary.

The fact that all those emotions are just amplified by being physically miserable right now doesn't speed up the sobs coming to an end, but finally Ivan pulls away enough to nod, though it isn't clear to which of the parts... But he heard hungry and warm and dry, and all of those sound like the man wants to feed him and find him a nice place to sleep, and maybe stay around for a bit. He can deal with everything else in the morning.
