I think the sealed court document might shed some light on things. That being said... her name is Carol Love-Smernitch

I Actually thought this too for all the same reasons. Was gonna write it but if i choose too many people well it's not a special guess. I said eh maybe they just making him look that odd to thorw us off. But i saw him too

A plot to make it look like a murder

The dude who was going to be Tiger Tiger is actually there to meet that other dude (Modern Love?) and maybe they have something to do with it

Are we sure it's not Clark's wife?

Again an entirely unnecessary reference to Modern Love, and that quote of his. It also would make sense that after being rejected by his wife, and by the person Clark had come to St. Louis, Floyd turns to the only person who's accepted him for who he is now, namely Modern Love. But how would that work, given that the police scrubbed Floyd's phone, so they'd have seen if he reengaged with Modern Love? Maybe he just went to see Modern Love at the Roller Rink, and it things progressed from there? We also know that Floyd had the drug that killed him, so Modern Love could've used it if Floyd brought it. It's not easy to piece together, but at this point with so many call backs, repeating that line so many times, there seem to be too many breadcrumbs for it not to be Modern Love.

does it literally mean the person across the street?
