Sonequa Martin-Green on "The Walking Dead" Season 6's Heart-Wrenching Return, Negan's Arrival

Hold on tight: Things are about to get bumpy on "The Walking Dead" Season 6. The show returns to AMC on Sunday, Feb. 14, and star Sonequa Martin-Green (Sasha) told IMDb the season "just keeps getting more and more intense, to the point where you almost can't stand it." Read on for a lot more, including teases on the arrival of Jeffrey Dean Morgan's Negan ("People are going to be overwhelmed"), the co-star with whom she'd most like to have more scenes, and dish on that one time Norman Reedus scooped her up for a motorcycle ride in the woods. — Gina Carbone
