Sometime around ten o'clock on Saturday night, a little lump-package is left outside Hamartia 602. It's made of a regular piece of computer paper folded and twisted to hold something. When unfolded, the "package" contains the two communicators that Oracle gave Rorschach when he first came into contact with the mask crew. Both have been turned off, but otherwise are in perfect working order. The only writing anywhere is the telltale pictorial signature written in pencil on the top of the lumpy package paper.
The next time Liz arrives at Phantasia, the bartender on duty flags her down and hands her a note. It's written in pen on a napkin that was clearly just taken from behind the bar. If asked about the note, the bartender says that Mike came in in a hurry, wrote it, and said that Liz had to receive it.
