Leon was so drawn into the magic of the program that he didn't really notice that GM had came back until the 'man' (or whatever GM was) spoke up to him. "Huh, what?," the disturbed man mumbled, turning around to see who was behind him. Oh, it was just GM, who finally came back from whatever he was doing down belo- OHSHITGMISBACK! To make things worse, he was quite obviously not happy to see Leon behind his laptop, and even less amused to see what he was doing.
"Uhm, I, uh, I was just...," Leon stumbled, obviously panicking and looking for an excuse -- and horribly failing at doing so. "I was just looking at things! And... playing around a bit. But mostly looking! It's just, I got bored and really didn't know what to do! You were off so long and, well, maybe I should've not touched your laptop, but you left it running and it looked so shiny and pretty and I just wanted to try it myself to see if I could make stuff work and thingies and-" 
Leon's rant was cut short due to something called needing to breathe. All the way through said rant, the only thought that went through Leon's head was [i]I'mgonnadieiI'mgonnadieI'mgonnadie![/i], put on constant repeat. Yeah, he was not feeling all that well p there at the moment. But then again, that has been the case for quite some while now, so eh.
"As for the dragon man, I thought to made a backup of it. See, I can be responsible!" To show this (quite pathetic excuse) to his master, Leon went to the File tab and moved the cursor to the 'Open' button. ...Sadly for the panicked Leon, his hand was trembling so badly he accidentally clicked the 'Run' button instead of 'Open'. "Uhm... whoopsie?," the young man spoke as he look around, now both afraid of GM's judgment and possibly dying in a horrible fashion (again, and quite possibly several times) due to whatever creature he has just summoned to this realm.
