"Hey, ya never know, right? Happiness shouldn't be impossible!" He'd picked up on Optimus' more sober mood and tried to say something that might help, slightly hesitantly reaching out to squeeze an upper arm... Even if Cliffjumper had no idea exactly how expansive Optimus' wish actually was.

"I mean, you never know what could happen, right? I shouldn't even be here an' whatever, so who knows what could happen for ya," Cliffjumper said with a shrug and then looked off out of the window; he knew Mirage would dispute 'shouldn't even be here' thing, but that was just the truth of it, right?

If Mirage hadn't decided for whatever reason... Then he most certainly wouldn't be here.
