This is the last day of fighting and Four has no idea who he is going to pair against Tris. She needs a boost in her rankings but can't afford to get beat. He is still deciding as they all file in and huddle around the board looking for their name. He hears Christina ask where Tris was and Four immediately gets worried that something happened to her. He briefly looks over his shoulder but finds she is intact so he returns his focus to the board.
He mentally scrolls through all the opponents who have a high enough rank to boost Tris' score but a low enough skill level to not repeat what Peter so brutally accomplished. Finally he determined there was no other person and wrote Molly next to Tris' name. They were last, hopefully giving her enough time to prepare mentally. Four turns and walks to the other side of the room to watch Will and Myra's fight. As he leans on the wall, he can't help but stifle a yawn from his late shift in the control room last night. No one could cover for him so he had to take it and he was feeling it right about now. He glances over at Tris as the first fight ends and he can see her mind busy at work developing a strategy.
Christina and Al enter the ring and Four hears him whimper, "Go easy on me ok?" He still has no idea what made that kid choose Dauntless. Al falls to the ground after a few quick hits and they shuffle off the mat. The next fight is one he's been waiting for. Edward is the only person here that can knock Peter down a few pegs and Four enjoys watching Edward kick the shit out of him. He stands a little straighter and moves a little closer as Tris enters the ring. Molly joins as well and sneers at Tris. 'Was that a birthmark I saw on your left butt cheek this morning stiff?" Four had no idea what she was talking about but from the look on Tris' face, whatever occurred to make Tris late involved Molly.
Four watched as Tris waited for Molly to strike first, ducked, and drove her fist into Molly's stomach quick and hard. Molly attempted to grab her but Tris slipped out of her grasp, and put her hands back up. He noticed she listened when he said her elbow was her best weapon because she forced her elbow at Molly's face but Molly was too fast, dodging it. Molly pulls back and punches Tris in the ribs and Four sees the same thing just as Tris sees it. Molly doesn't protect her face and Tris is smart enough to exploit that. Tris attacks with an uppercut toward her stomach, and then immediately sweeps her legs out from under her. Four can tell she has been practicing and listening to his suggestions, her fighting is much improved, or she has a personal vendetta against Molly. He is proud of her until he sees her snap and go into a dark place. As Molly is on the ground, she continues to kick her even though the fight is clearly won. Four feels a rush of panic as he thinks of Marcus and rushes over to pull Tris off from her.
Four clamps his hands around her arms, attempting to pull her back, as she gets one last stomp in causing blood to spurt from Molly nose. Four wrenches her away and mutters, "You won. Stop!" Four can't believe the look in Tris' eyes, such a fury aimed toward Molly, and he knows she has to leave this room immediately. "I think you should leave, take a walk."
He looks at Tris and sees her snap back to reality but can't find any guilt on her face. "I'm fine now, "she answers him as she pulls away.
