Reno didn't hold any love for Flauros either and he suspected the feeling was mutual. In fact, he was a little wary of the invitation, but he was a little paranoid by nature. Trained to be aware and suspicious of everything around him at basically all times, anyway. It would be going too far to say that he really thought this was a trap; it was no less trustworthy than any other situation, really. And so he showed up a couple minutes after Yako, hands in his pockets, weapons safely in their place, and with a general air of not really wanting to be there.
If they had known him better, they would know that was about how he appeared to anything that constituted "work." But at least he seemed to sort of be considered part of the team now, and that was something. He'd listen to whatever Flauros had to say.
