For all of the ranting, Marco just blinks and eventually bursts out laughing, taking the balloon of fake blood and gently catching it in a wing so as to avoid it getting all over him. He set it down and scooped up his chameleon brother in a too tight hug. Invisible or not, Espio was loud as hell, and it wasn't hard to figure out where the balloon came from.

"Sorry, eh? Calm down. Next time, clue me in first. You told Grell and not me? You know I'm always up for pranks." At least when he's not at the receiving end of them. "And jeez, if you're stressed out you can always just talk to me, you don't have to hold it all in until you explode. You're turning into Ace on me. But with a tail instead of flames." He affectionately snuggled his adopted brother and refused to let him go.
