We don't know they haven't said that. If Richie is saying he talked to Jon recently, that may be exactly what they did. They don't owe us details of their personal conversation or interpersonal relationship.

Maybe something like Christina Grimmie's murder was a wake up call to both of them (and I'm speculating just as much as the rest of you), not just to how some deranged fan could try to settle whatever score he thought existed between them but to how fragile life and relationships are.

In my life, I've found that when you've been friends with someone for 30 years, you pick up the phone, even after a few years have passed, and you pick up where you left off.
