This time it was Starscream taking in those words. He hummed, hands flat against the metal expanse of those wings for a moment. Did others bond like that in his reality and he just not know about it? It was possible. As friendly as Starscream was, he didn't intrude into the personal lives of others when it came to issues of the ember.

"We... We do have such a thing as a split spark. Sideswipe still has a brother on the Autobot side of things. Jazz and Ricochet are as well, I believe. Though I am not sure I have heard any bond like you describe."

He paused, leaning a bit over Thundercracker's shoulder to catch a glimpse of him. "You have one, I take it."
