"Oh, my god, Halsin..." Finnick murmurs. He had no idea Halsin was there with them and watched it happen. He drifts in the water to get close enough to wrap his arms around Halsin's shoulders, embracing him gently.

"I'm so sorry... That's terrible." Finnick's heart hurts for him. It reminds him of watching Mags die, and that felt like the ground had collapsed under him and plunged him into a void of darkness. He didn't want to go on. No wonder Halsin is in such rough shape. He just holds him in the hug, hoping it might comfort him a little.
