echo runs cold as a result of what was done to him on skako minor. wrecker runs hot as a result of the enhancements made on him when he was being grown in a lab on kamino.
headcanon that echo slowly and subconsciously becomes very close to wrecker because of how warm he is. he’s a warm presence in both body and mind. he’s kind and almost always cheerful. he’s already very physically affectionate. over time, echo finds himself just leaning on him in quiet moments. sitting beside him on the marauder on the way to missions. and on nights where he can’t sleep, either from being cold, nightmares, or both, he shuffles over to wrecker’s bunk. wrecker never pushes him and just holds him to give him his warmth and presence.
echo loves his (big) little brother so much
