This week on Marvel’s Agents of S.H.I.E.L.D., Skye (played by Chloe Bennet) gets a better grasp on what her gift is and isn’t, as seen in this exclusive sneak peek.

In Tuesday’s episode (ABC, 9/c), Afterlife boss lady Jiaying (played by Dichen Lachman) — who unbeknownst to Skye is her mother — invites the retreat’s very special new arrival to explore her power. But does Skye have what it takes to literally move mountains?

Elsewhere in the episode, titled “Melinda,” May’s juggling of her loyalty to Coulson and mounting valid points made by the “real” S.H.I.E.L.D.’s director Gonzales triggers flashbacks to when and how the kickass agent “earned” the nickname of “The Cavalry.”
