Anger/Sorry (whichever you prefer)
"You know what? Fuck you, Jethro! I'm doing the best I can, alright!" Tony shouted, his face red and his fists clenched at his side.
"Well obviously your best isn't good enough!" Jethro shouted back, his arms crossed over his chest. Tony barely managed to reign in his anger at the man in front of him.
"Maybe if you hadn't up and quit with no notice, we wouldn't be having this damn problem Jethro! I'd actually be able to be home to see Katie before bedtime, and-"
Jethro's cheeks reddened and his hands tightened into fists atop his arms. "And maybeif I had recommended a more competent team lead to replace me, then Abby wouldn't be laying in a hospital bed at Bethesda right now!" As soon as the words were out of his mouth, Jethro regretted them. He cursed himself, but he couldn't take them back so he stood his ground. Tony was the only person in the world that could make him lose his cool enough that he didn't think before he spoke.
Tony stepped back as if Jethro had struck him, and leveled him with a frosty glare. Jethro didn't even try and protect himself from the slap that landed on his cheek. He damn well deserved it. Tony stepped back again, one hand covering his mouth and stared at the hand that had just connected with Jethro's cheek.
"Oh God, Jet, I'm so sorry," he said, voice thick with pain.
"Don't apologize," he said gruffly, "I-"
"It's a sign of weakness, I know," Tony whispered, refusing to look at Jethro.
"Nah," Jethro said, taking a step toward Tony. "I damn well deserved that. If anyone should be apologize, it should be me."
"No, you're right. It is my fault Abby got shot. I couldn't protect her, I should have fucking protected her! They are my responsibility now," Tony said, his voice wavering. He covered his face with both hands, and his shoulders started to shake. Jethro swallowed his pride, and wrapped his arms around Tony's shoulders and pulling his husband, unresisting, against his chest.
"No Tony, I was wrong. And," Jethro closed his eyes and pressed his cheek against the top of Tony's head. "I'm sorry."
