JJ's final call to Falco? (spoilers)
Rewatching this fabulous classic again, I was struck by the question:
why does JJ actually leave a message for poor Falco to meet him at his apartment?
Of course it's needed to set up the dramatic final events and all the revelations, but why would JJ want to see Sidney where his sister would probably be within earshot?
There's only one answer that fits - JJ was planning to throw Sid under the bus all along - he wanted his sister to think that Falco had acted on his own in framing her boyfriend.
And since JJ was obsessed with his own sister, he probably felt it was credible that other men would be jealously obsessed with her too.
Thoughts?
