The Odyssey

S1 E14: After Oliver is shot, he turns to a surprising person for help Felicity. Diggle is stunned when he sees Felicity walk through the front door of the lair dragging a dying Oliver behind her, and the two team up to save Oliver's life. As Oliver hovers between life and death, he flashes back to a seminal event on the island -- a daring escape attempt with his new friend Slade Wilson (guest star Manu Bennett -- Spartacus).
