My guess is that Brett will actually commute back and forth, maybe there will even be some sort of one week on / one week off situation which allows her to try to readjust to Fowlerton and enjoy her time with Kyle, while also letting this new paramedic come in here and there.
It’s not impossible, either, as Fowlerton and Chicago are less than four hours apart.
But, that new ambo crew member (who’s been described as “Anderson Cooper minus a couple dozen IQ points”) will only be around in a recurring capacity this season.
