Ya have to love writers who make sure that our hero has to come to the rescue of Gene, who is such a pig to our guy so often.
Loved the bit where he asks Sam to be the "picky pain in the ass you usually are" on his behalf. And Sam justifies the idea. "Whatever he is, he's not a killer."
How odd that the temporary DCI is, on the surface at least, running things probably more like how Sam would really like them to be. But now he can't really like it, because it doesn't bode well for Gene. Plus, now the guy seems to be acting, well, suspicously. But, that could just be because he assumes he needs to be wary of the team because they'll try to get Gene off even if he did kill the guy.
