His focus still adjusting, Donnie hadn't even really noticed someone there in front of him until Mark speaks up. He nearly goes running into the bench as he tosses his arms up, stumbling in an awkward, surprised jump.

'Who' would be the next reasonable question, but he's still trying to round his thoughts up as he clings to the end of the bench, staring at Mark as though he were the one that had just suddenly appeared. The camera's display is turned towards him and Donnie slowly pries his eyes from the guy to look down at the image there.

"What the-"

Sorry, he's going to grab that camera for a closer look. That is undoubtedly him, which is weird, and the guy's question is way too on point to be a casual curiosity. Donnie's brow twitches. What is going on here? Where is here anyway, wasn't he supposed to be doing something?

"Okay, how'd you get that picture? And have you been here the whole time? -Or have I been here the whole time..?" His brain's picking up back to usual speed then, the edge coming off of the last question as he distractedly hands back the camera so he can look at his own hands as though they hold all the answers.
