Rigsby! No one's that nice and now I have undeniable proof!
S06E02
Point 1: At 30min into the episode, Rigsby is in Lisbon's office getting the assignment to go across town to try get the files. Look out the windows, it's day.
Point 2: Around 33min, the whole team, minus Rigsby, is having a pow-wow about the current case. Look out the windows, it's night.
Point 3: 38min, He's at the house, calling Lisbon about the files. Look out the windows, it's day again.
It doesn't take an overnight trip to get to Dr Miller's house. There is a 24hr period that Rigsby is MIA during a cross-town task. Ain't nobody can explain dat!
