He tells us about Johnny and Mac but thats about all I could understand. Theres also a new icon in the top right corner of a pocket watch, so I assume that the first shadow was Mac, when you click on the pocket watch it replays the text that the previous shadow gave when you clicked it!
Here are the screencaptures, including the countdown loading screen!
To have less images I copied and pasted the text onto less screencaptures. For example the second screencapture has the text from when you click the shadow once and twice.
EDIT: Its been pointed out that Jackie also wears a hat! And judging by the comments, most people think it is Jackie! Sorry for the confusion /(^-^)
