"I think the term is ladies first, and not men first." Sonic replied, slowly approaching the bed. Yet, he refused to get on it, as exhausted as he was, wanting his sister to get comfortable before he did himself. His legs felt weak from exhaustion, and Sonic wondered if the the scientists in their last experiment gave him some kind of drug. It wouldn't be the first time Sonic was given drugs that did this to him, but it would be the last time, and Sonic wanted to make sure of that. Knuckles chuckled a little, watching the siblings talk about who got to get comfortable first. They were protective of each other, and the two of them only had each other as family. So, Knuckles understood why they were so protective of one another, because the other one would be alone if something happened to one of them. After watching for a few more moments, Knuckles headed off to his mattress, leaving the two siblings alone for the night.
