"Hey, how long are you going to cry?" Cale grumbled petulantly and Perez sniffled and wiped his eyes.
"I have a sweet tooth, what can I do?"
Cale sighed and looked at Perez's bloody hand. When they reached the end of the cave after showing him the memories, Perez tripped and fell to the ground.
He started to cry because his hand had been cut. Cale knew he wasn't really crying over a cut. He knew that he was still crying because of the memories he had given him because he was still under the influence of the memories and the emotions that went with them.
Perez felt sorry for the times when Cale was alone, but it was clear that this crying was disturbing Cale. The past was the past as there was no cure for what had happened and what was dead.
Even though Cale had once been hurt, he had refused to bury himself in his pain and had chosen to move on. It was the right choice to make.
