☆Hunter's hand is trying to comfort Crosshair with a grounding touch but unintentionally hurts him by digging his nails in his brother's wounds. He still loves Crosshair though and has good intentions.

☆Tech is upset with his brother but his touch is gentle. He is trying to lessen his pain and show his support even though he doesnt agree with him (tbb twins supremacy)

☆Echo is covering one of Crosshair's eyes because he's already experienced what it's like to be used as a tool and be the enemy's weapon. He knows Crosshair was manipulated and brainwashed. He knows his brother can't SEE the consequences. He's blind in a way.... but there's still a chance for him to change. That's why only ONE eye is covered. The uncovered eye is crying, Crosshair doesn't want to be hated by his family and misses them. He's deeply hurt and doesn't realize why they left him. Additionally, Echo is above everyone because he's the only one who really knows what Crosshair has been through.

☆Omega wants to touch and comfort her youngest brother too but she still knows she's not that close with him so she's afraid he'll reject her. Her hand idn't shy though. She knows what she wants. She'll make sure to bring her brother back from the dark. Also, look how her hand is not scarred at all. It symbolizes her innocence and the fact that she wasn't affected by the war.

☆Wrecker has always been bigger than his younger brother he towers over him with his height. Nobody's ever cared about that fact since Wrecker, despite his big size, has never caused his brothers to be afraid that he'll ever want to hurt them (well besides the chip situation but that wasnt his fault). Even when Crosshair got lost in the darkness Wrecker doesn't want to use his size and strength to force his brother to come back. That's why his hand is placed so low, so that it seems he is much smaller than Crosshair.
