The heavy thudding on the door paired with a hand fumbling at the latch raised every primal instinct in his body to attack. Mako faced the door with the burning impulse to rip through it and dismember the man on the other side.

The man who'd been affecting his marriage, hurting his wife, making her feel uncomfortable in their own home. He was done putting up with this utter shit that had been hurting them, breaking down Korra from the strong woman he fell in love with to one who looked over her shoulder everywhere she went. It made him sick to see her like this and not be able to do anything.

Some days Mako almost wished he'd attack to give him an excuse to kill him.

"Get out!" He used the deepest, scariest voice he could to get the asshole away from his wife and their precious baby. The slight pause gave him naïve hope that was suppressed with the louder, more erratic shouts from the next room.

"You've ruined her! You're keeping her all to yourself."

Anger wasn't a strong enough word to describe the pure rage welling in his chest as Mako faced the door and the angry pounding coming from the other side. He wanted to break through the door and shoot him, but Korra came first. Their child came first.

"Korra." Mako reacted as fast as he could with his heart racing. This was vital, this was important, the two of them were his family; they and Bolin were all he had in the entire world. "Just, make sure that the baby is ok." Meaning to stop her from fighting, he winced when he realized he'd given away the presence of their baby, a heavily guarded secret in Republic City. Virtually no one knew.

"What!?" An angry yell came from the other side of the door. "You did what to her?"

"Shit." Mako barely had time to hate himself for the mistake when the door gave way and the man flew at him. It was almost therapeutic to slam the asshole into the floor, to fight him and wrestle him to the ground. There was no struggle of strength, there was no real fight, he was no opponent, and Mako felt slight disappointment at that.

Nor did he hold back when it came to pinning him against the ground, pressing down on him a little more than he would to another criminal. And he didn't care when his colleagues arrived he was rough pulling him up off of the floor, he didn't care when the asshole's face hit the doorframe.

All he cared was getting his wife into his arms, but first he had to explain what had happened at least four times. Korra had to answer questions about what she'd seen and was holding her arms around her body.

Mako just watched her and hated every second of her defensive positioning. Before this, Korra would have had her hands on her hips, powerful, ready to take on anything. But she looked tired, so tired and scared and he hated it. He hated the bastard who hurt his wife.

So when she requested they move he agreed without hesitation. He'd do anything to make her feel safe again. He couldn't make their apartment safe, he'd move to the South Pole if that's what she wanted.

The Avatar could live anywhere. Korra could go anywhere. And Mako wasn't going to leave her for anything.
