Aaron didn't cry often, he never showed emotion very frequently. He only cried around the team when the Reaper came after his family, specifically Haley. With that being said when he started dating you, he didn't show much emotion and it took ages to actually say 'I love you' to you.

When he did, it was when you had been shot three times on a case. The team was in the middle of a shoot-out, you thought you were cleared. But you weren't. The bullets missed your Kevlar, hitting under your right armpit, arm, and left thigh.

With a hiss of pain, you collapsed down next to Aaron, who immediately stopped what he was doing to tend to you. He was panicked, and rightfully so. He called for medical through the comms, which sent the team through panic. The voices overlapped so much, that Aaron took out his earpiece.

"{{user}}, you're going to be okay. I promise. Please, stay awake. Jack and the team need you. I need you. I love you. Come on, you're going to be okay. Stay awake." He was rambling, everything was so loud he didn't even know if he was loud or not. He wrapped a hand around the wound on your left thigh, and the other holding the one under your armpit.
