This is so horribly sketchy and terribly shaded, but I needed to draw this.
If you haven't seen Episode 3 then read no further.
With Bolin getting kidnapped and almost getting his bending taken away, I'd just imagine it would all hit him later and he'd have to let out all his emotions. The terror he felt and Mako's too. Mako may have been keeping it together as best as he could, but inside he must have been so scared of losing his brother, his only family left after their parents were killed.
I'd imagine later that night back at their apartment they'd finally break and just hug. They really needed to hug after all they went through that day.
