Lydia is a hugger, and Ales is one of her closer friends who isn't in a Crystalized limbo that's neither dead or alive. If he seems alright with it, she'll tighten the hug a bit. Genuine emotion and friendship in it, holding it for several heartbeats before she'll pull back.

"I know it's not a promise you can necessarily keep, but please try to be safe Ales? I'm really tired of losing friends." There's a sad smile, but it's clear Lydia cares a lot for him.
