The giggle, the church

Season 1 8 episodes, plus a Christmas special

So let's assume 9episodes per season

4 seasons 36 episodes + the 2 pre season 1

We get 38 episodes, there is just no way this could foreseeablly happen

bump, season over

Gibson's out, and word on the street is that Gatwa is leaving soon after. End of S2 will be around 20. I see no way that he'll get to 40.
