Con O'Neill in "The Tunnel" Series 2 (2016)

Con O'Neill plays Neil Grey in episodes 2.06, 2.07 and 2.08 of "The Tunnel." I think he's British intelligence of some kind? TBH I only watched these three episodes, so I don't have a ton of context. Whatever he is, he can wheel and deal on the behalf of British authorities regarding crime lords and some big scary "Chemist" character who tortures people via, y'know, chemicals. This video contains: a syringe that was recently injected in someone's eye near the end of the video, if you hate that kind of thing. Also multiple people being shot. And Con yelling "FUCK!"
