Of course. I don't think Yamagi really had anything else planned for the whole arrest thing. From what I've noticed so far in the Rp, battles don't seem to be illegal per se, it's just where it's taken place. I can't really see Darren getting into much trouble, since his Machop had physical attacks compared to Gible.
And yeah, the reason why we did joint posts, is because we're both new at it. But after seeing the one Jegretis and Albunnie did, I think I've got the basics of it. Wouldn't mind whichever one you choose.
