Judgement Day is fast approaching for Warehouse 13‘s Myka, and that can only mean one thing — that Faran Tahir (Star Trek, Iron Man) will be reprising his role of Adwin Kosan, one of the most powerful Regents, the shadowy group charged with keeping the Warehouse in good order.

In fact, TVLine can confirm that Tahir resurfaces in the Syfy hit’s very next episode, “Trials,” airing Monday, July 18, at 9/8c.

The specific circumstance precipitating Kosan’s visit: It is up to him to determine whether or not Myka (played by Joanne Kelly) is fit to return to active duty. (After all, a gal who up and quits Warehouse duty can’t just show up and grab back her keys to the very, very well-kept secret.)
