Wildcard Who Saved the World: Eddie Thawne went from a side character to more of a leading man as The Flash Season 1 progressed. We never did learn exactly how Harrison/Eobard viewed his ancestor, but how Dr. Stein saw him was brilliant: He called him a wild card, the only person who got to choose his own future, making him the most important in the group. And choose Eddie did, taking his own life to eradicate Eobard Thawne from existence. He decided to be the hero he knew he was for Iris, the woman he loved. It was tragic, yet exactly what we should have expected from the man we'd come know.
