The Tomorrow People alum joined the cast in season 2 as Lincoln, a charismatic Inhuman who helped Skye (Chloe Bennet) discover her powers, and eventually sided with S.H.I.E.L.D. after Inhuman leader Jaiying incited a war between them. “We loved Luke this season,” executive producer Jeffrey Bell told EW when asked if the show was planning to keep Lincoln around. “We have a lot of ideas for Luke… He was a nice addition this past season, so he’s definitely being considered for all that.” Marvel’s Agents of S.H.I.E.L.D. will return to ABC this fall.
