They'll never give us this scene but imagine Clarke coming back and watching Bellamy's training sessions. Then one day he's looking for another spar partner and she steps forward. He's confused but intrigued, he knows that she learned a lot in those 3 months. So they begin, everyone watching them. Miller and Raven place bets. The scene plays out like it does in Pacific Rim, neither of them refusing to back down. Tension increases w/every pin. People are uncomfortable but can't stop watching.
