What time in the 2nd half do the stands clear in Jordan-Hare?

I'm not sure if the Aubbies will stay until the 4th quarter, but I'll give them the benefit of the doubt and say at 9:30 of the 4th after a punt return gives the Hogs good field position with a 10 pt. lead and we begin a slow rolling time consuming march down the field to take a mercy knee is when the empty seats replace another set of dejected baseless tiger fans. Purple and Yellow, Navy and Orange, Black and Yellow the colors change but the defeated stay the same.
