Hn. A lunatic with explosives.

[He still isn't sure, though. Would Rex be acting up if that was all it was?]

Back home we had a gang running loose, called themselves Powder Gangers. They were just escaped convicts who got hold of explosives. Rex never had a problem with those. Unless... maybe this is some alien he doesn't like the smell of.

[He doesn't know much about the aliens around here, so maybe there is one that would put Rex on edge. He has to remember where they are.]
