Luke Mitchell joined the cast of Marvel’s Agents of SHIELD after the half way point in the season. He plays Inhuman Lincoln with electrical ability. We first saw him help Skye through her transition to being Inhuman and then introduce her to Jiaying, Skye’s mother. Lincoln eventually turned on Jiaying and helped Skye and the rest of SHIELD stop her plan on releasing the Terrigen Mist.
With Skye getting the folder marked Caterpillars at the end of season two, it is possible that Mitchell’s expanded role may be as part of Skye’s team of super-powered agents. Prior to joining the Marvel production, Mitchell was on the Tomorrow People.
Marvel’s Agents of SHIELD returns for season three this fall.
