Just want to clarify that the op about the "man in the mirror" was referring to a YT re-post of a video of the apt. building where the murder happened. The original video was filmed by just some local Montreal dude and posted on YT by matty pantaloons which is, presumably, that same dude who originally filmed it. It was then re-posted by BB on YT with his own edits, as if BB himself had filmed it.
That vid shows a man in a mirror (at 1:03 I think). When BB reposted it he specifically pointed out the guy in the mirror and the time stamp as if to say BB could not possibly be one and the same with LM b/c the filmer obviously looks nothing like LM.
In any case, that video and the man in the mirror has nothing to do with Paris or the dude/john LM hooked up with there. Sorry. Just don't want to start rumors about Paris mirrors lol. It's confusing enough as it is!
