He did just as he was told, silent, intent on Merlin. He was still Eggsy, but he respected his life as a Kingsman as well. Even if he was good for smarting off about it as well.

Eggsy didn't even think, reaching out and stroking his hand along Harry's arm, reminding him he was there, holding him close. Not saying a word until he felt certain he was asleep again.

"And what if he's remembering things wrong," he asked in a soft whisper. He hadn't even meant to but then the words were there. "What if we're like messin' up his memories somehow?"

Or, as he wasn't saying. He. What if he was messing up Harry's memories, making him believe he felt something he hadn't before? He wasn't even sure that was possible, but it was a fear he had.
