First Garrot's surprised that the wild elves don't have a word for grandpa, but as Gyre starts sighing and emphasizing that he shouldn't do that, it's even clearer that there's some weird baggage here. He's confused, he's sad, and as Gyre's head meets Garrot's chest, that arm just squeezes him a little tighter.

"You don't have to tell me at all, and I'm used to late nights." His tone is the warmest and most compassionate fuck-you he can manage. "Take as long as you need, I'm here as long as you want me to be." See, Garrot's always had his family to fall back on, to help fix his mistakes. And it sounds like Gyre doesn't have that, which is bullshit because he should!!! Sure Gyre's a bit of a prick, but he's a badass and clearly a good guy! So Garrot will wait, and he'll continue resisting the urge to snatch his friend up and full-body hugbear the sad feelings out of his spine.
