Alex (Justin Chambers) appears to be digging his own grave on Grey's Anatomy.

In a sneak peek from the Season 13 premiere, Alex is (understandably) worried about DeLuca's (Giacomo Gianniotti) condition. So he enlists Meredith (Ellen Pompeo) to sneak a look at DeLuca's scans to see just how much trouble Alex could potentially be in after beating him up.

"Alex, this is really bad," Meredith warns him, as if that wasn't obvious enough already.

And it's about to get worse - when Alex encounters a suspicious-looking Ben (Jason George) in the hallway, he makes a decision that can only be described as ill-advised, at best.
