The call to catch caught his attention, causing Damien to spin on a hell and face the direction of her voice. And without much trouble at all, he would proceed to catch any fruit she threw down to him. Perhaps this was intended as a peace offering for her father, who hopefully had a soft spot for ripe fruit.
"I'm sure your parents must have had a hard time getting you down from there." His comment was backed by an amused smirk, because clearly he was enjoying the downtime and more so the fact he was spending it with her. While he waited for Fiorella to scale back down the tree, he examined the fruit he was holding. Everything about it was foreign to him, from the way it looked and even the smell. Though he was never so distracted that he wouldn't be able to help her down if necessary, or catch her in the event of a mishap.
If anything, he was glad for her persistent interludes to tease and provoke him. It helped break up any potential uncertainty, and instead allowed him to reorient himself mentally and get his bearings. So it was no wonder that he seemed to be in his element again, and just in time for whatever was going to happen on the other side of those gates.
