Don't hurt him? What does Ronan think he's going to do? He can see the vague outline of Ronan with his arms out, a shield, a saint demanding that swords be laid down.

"I freaked you out? Jesus Christ--"

Declan doesn't know what hits him but it knocks him to the ground, hard. The blade ignites and as adrenaline dumps into his system, his power manifests again. The curtain of it falls and the menacing red that had been illuminating Kylo's face goes out.

Alright. Okay, he can see how this is going to be beneficial. He still doesn't like it, but it's useful, and utility matters more than anything else. Declan gets up slowly, more ready this time.

"Ronan, are you okay?"

He'd gotten a slightly better look at the other figure and Declan braces himself on the off chance that what follows next is a blind attack.
