Normally Thundercracker could sit for quite a while and just listen to the twins play games, but with a little bit of the high-grade in him he decided that he was tired of listening, and moved away, intentionally not doing anything to worry them. He had heard another person in the room earlier, but hadn't thought much of it as he had been listening to the twins banter, but now he wondered who it was and what was going on.

He wandered over to the couch Chromia was on, standing near one arm hoping to find out who it was before he did anything else. "Hello." He said, the greeting fairly neutral, but he would be able to figure out who it was from the voice.
