It all sounded like a nice night out to Selwyn. Bored most of the time as he continued to hide out in a cottage he had taken for his own, he wasn't inclined to go out and seek much excitement. But when the Lestrange brothers proposed a trip to the Ministry for a little death and destruction, then he was all for it.
Not to mention he really wanted a new chair.
As they took the floo into the middle of the Ministry and made their way through to the DMLE, chaos was already waiting for them. There was nothing more he hated than the unexpected, and Selwyn looked displeased with this turn of events. Allowing the rest of the group to push past him as he faded towards the back, he wandered away, finding the lifts and picking a floor at random, uninterested in being part of something if he wasn't guaranteed to win.
It was dark and quiet where he found himself, all of the offices unoccupied and empty. Well, almost empty. Spotting a rather nice red leather chair behind one of the desks, he surveyed it for a moment and then decided he wanted to have it. Casting a charm to minimise it into a transportable size, he headed back the way he came and exited the Ministry.
