'Forever' First Look: Ioan Gruffudd Strips Down!

ABC

Star Ioan Gruffudd gets naked in the Dec. 9 episode of ABC's rookie procedural.

Forever is showing some skin.

ETonline exclusively debuts two first-look images from next week’s episode, aptly titled “Skinny Dipper,” which find handsome star Ioan Gruffudd, as the immortal NYPD forensic expert Henry Morgan, getting down to his “skivvies” – and it looks like he prefers boxers over briefs.

It’s not all for show though, as Henry takes matters into his own hands after two innocents fall victim to “Adam,” his secret stalker. And of course, Judd Hirsch’s Abe – Henry’s best friend and adopted son – is roped in to the mess.

If anything, the photos raise questions: What exactly were Henry and Abe about to do? Why is Abe carrying a flashlight?

The episode, set to air Dec. 9, is a big one as Henry finally tracks down the true identity of his stalker, who has been menacing him since the start of the series.

Forever airs Tuesdays at 10 p.m. ET/PT on ABC.
