Humans' Limits 0092- Found it

The surprise in Lucas' red eyes was genuine as he looked at the gaunt 1.70 meter tall man that lost his breath with a rifle, an AK, gripped between his stiff fingers.

"Someone you know?"

The sulking Estrella had come beside him at some point. He explained without turning to her:

"Yeah, the leader of my old unit. I was right when I thought he survived."

"Well, now he is dead."

Lucas fixedly looked at the unmoving man. With how his cheek bones were obvious, he shouldn't have been treated that well even after surrendering. That must be why he was among the weaker ones of the group. He suddenly turned to Estrella before asking:

"Take back your cold."

By becoming some kind of representative of the cold, after gaining control, she could absorb it too instead of just letting it out.
