"He didn't think any of us was operating in the best interest of the band. I asked him what he meant by that, and he said, `Well, you know, when y'all did your movie,' meaning Joey (Fatone) and me (and their 2001 film On The Line)...
I wonder if that's a direct quote from Justin. Because reading "any of us" makes me think Justin includes himself. Maybe he felt that he, along with the other guys, wasn't operating in the best interests of the band. Maybe he thought they had other things they were working on as well and the band was no longer most important.
