The last Northbound 21 terminates at Pilgrim St to become the N21 and the last N21 becomes the 21 so it makes perfect sense for Chester to operate it as opposed to Gateshead at least imo
The last N21's arrive at Chester-le-Street at 4.45am from each direction (Durham and Newcastle), but the first 21 leaves Chester-le-Street at 4.37, meaning the last N21 can't become the first 21 of the morning.
