Was thinking about this again.
The two are just being flirty and cute, like usual. Titan wants to get Eclipse flustered with some cheesy romantic gesture. He takes Eclipse's hand. He brings the back of Eclipse's hand to his mouth.
Eclipse draws back immediately, horrified wide eyes flashing. His 'breaths' quicken, almost to the point of hyperventilating. He seems to be staring through Titan, as if not fully seeing him there anymore.
Titan's expression drops instantly. He cups Eclipse's face. "Hey. Hey, what's wrong? Eclipse?"
Eclipse shuts his eyes and gives his head a small shake. Yet, this barely seems to calm him, just enough to be able to reply. "N-nothing. Nothing. I...I'm sorry."
Titan guides Eclipse's stare into his own. "Eclipse. Don't lie to me. What happened just then?"
Eclipse is silent for a brief time. His 'breaths' only starting to calm down and his body still shaking. When he finds his voice, he can only muster, "S-something Solar used to do." Then, the adrenaline pushes him further. "I-I didn't even ask him to! He- he would just...do it, a-and I just, I-I-I-"
Titan pulls Eclipse close against him. "Hey. Hey. Breathe. Just breathe, Eclipse. It's okay. I'm sorry I made you think about that. I mean, I know I had no way of knowing, but...I'm still sorry I hurt you."
Eclipse's 'breathing' finally begins to settle. He pulls himself even further into Titan's hold, adding his own tight grip.
