Scott Elrod is checking in to Chicago Fire.

The actor, best known to Grey’s Anatomy viewers as Meredith’s army doctor of a love interest, has signed on for a multiple-episode arc with the NBC drama.

According to multiple outlets, Elrod will appear on Season 5 as “lifestyle” celebrity Travis Brenner.

That's... different.

Look for Elrod’s character to drop-dead gorgeous (sort of hard to avoid when this actor is playing with) and to have a million Instagram followers.

He and Severide will cross paths on a fire call, after which the rescue squad lieutenant will be tempted to join Brenner’s fast-paced inner circle.

It certainly sounds like a unique direction for the series to go in.

In addition to his Grey’s Anatomy role as Dr. William Thorpe, Elrod’s television resume includes stints on The Young and the Restless and Men in Trees.

Chicago Fire Season 5 premieres Tuesday, October 11 at 10/9c.

Here is a look back at how we felt about Season 4:
