Once he saw Merwyn was able to stand, Greg heaved himself to his feet without needing to use the offered hand. It didn't occur to him that it might seem rude to refuse - he just didn't need the help. "It's okay," he emphasised when he could get a word in. "You didn't mean to." For all that, he wasn't going to refuse an offer of sweets. Greg's loyalty couldn't be bought, exactly, but if there were no existing conflicts it could certainly help.
"Some toffees," he said honestly and then, belatedly, "thanks."
