Sonya chuckled just as the Echidna had managed to wake up from the effects of tickling his nose. Nodding, she handed him the apple, before taking a bite out of her own. Of course, she let Sonic speak first, though it didn't surprise that the nightmares of the lab continued to plague. Truthfully, she was the one who took most of the punishments, while he was the first to be used for experiments. Whenever they were proven successful, she was to be next to be examined for when the female mobian anatomy was needed, after the male. 

As a result, the trauma was still imprinted within the younger's mind, evident in his squeaking and twitching from last night. Even in his sleep, it will continue to haunt him. If he needed to, Sonya will gladly be a listening ear, and understand his troubles. She will support him the rest of the way, and slowly try to erase it.
