That's exactly the thing that's so great about Joe - he clearly respects the other characters. He tells them stuff, instead of hiding it from them (for long, anyway). I'm glad you highlighted that here.

Also, I think it's usually phrased "Absence of evidence is not evidence of absence."

This is a superb character analysis of Cisco. Just one question... did Caitlin just have a pregnancy scare or did she have an abortion?
