he had been mulling it over for a little while after the multiple changes at the station, from on-air personalities & execs/mgmt

someone must have tipped Angie off, cuz she was ghost

I think Cipha alluded to this the last time he saw Jay-Z (me speculating) but he said Jay-Z was asking him real darted/focused questions about radio & programming etc.

Juan EP is still alive & well as it's not directly connected to Hot97, they just used Hot97 to connect with artists going/coming through the station

or they scheduled certain celebs who aren't on Hot 97 to come to the studio to do interviews.

Ciph was loyal & took some time to think it over after talking to Rosenberg on air.
