First Aid is quiet for a moment, but he's trying to parse what that could even mean, fighting with a growing headache and the achiness of his body setting in. The warm tuck of Sixshot's head under his arm is a good distraction from just going to sleep again though.

When it clicks, First Aid laughs. It's an airy, painful sound.

"That's what this is about."

He does remember Tarn's anger. Some of the conversation was starting to click in his memory. At the time, he didn't really pinpoint the last straw being well... that.

"During... the outbreak, I found him. He asked for my help." He didn't have the energy to be embarrassed, but he had been. He regretted his actions when he ran into Tarn. A large part of him was ashamed. "I used my hands. I... insulted him. He was... embarrassed."

Then the shame does hit him like a shower of molten slag. He turns his head up at the ceiling. He hadn't really wanted to tell anyone that, but the way Sixshot had phrased it he was seeking an explanation. It wasn't one of his best moments, topped only by killing Pharma.

Funny almost dying over though. He figured it would have been something else, like finding out he was part of a spy network infiltrating them, or the closeness to Megatron, or his poorly hidden gross crush on the phase sixer near his side.
