Last year when Marvel announced an Inhumans movie for 2018, not many people outside comics fandom knew what an Inhuman was. So Marvel has been using various channels to introduce the concept of the mutant-like characters to broad audiences. We’ll probably see a couple in Avengers: Age of Ultron when that film opens in May, but for now the bulk of the Inhumans outreach is being done by Agents of S.H.I.E.L.D. Luke Mitchell, of The CW’s show The Tomorrow People, has just been cast as an Inhuman named Lincoln.

(Some potential spoilers follow for those not caught up with the show’s current run.)

Marvel.com announced that Mitchell is now “a charismatic Inhuman named Lincoln, who has an important role to play in Skye understanding the true extent of her transformation.” We don’t know precisely when he’ll show up, but it’ll be sometime after the show’s March return. (Obviously.)

That “transformation” for the S.H.I.E.L.D. character Skye (Chloe Bennett) started to manifest at the end of the show’s mid-season finale. The nature of her storyline for the rest of the season is open to question at this point, but Marvel’s open announcement about the nature of Mitchell’s character lets us know they are prioritizing the Inhumans as a plot point.

In addition to his role on The CW’s The Tomorrow People, Mitchell appeared on Australian soap opera Neighbours. Agents of S.H.I.E.L.D. returns to the air 9 p.m. Tuesday, March 3 on ABC.
