Due to the nature of the show’s production, there hasn’t been two separate heists, each spanning across two seasons for a total of four parts. While the first heist more or less went to plan, the same can’t be said for how we left things inside the Bank of Spain at the end of season 4. Nairobi’s (Alba Flores) execution was a major riff in the closing episodes, shattering the core team and exacerbating the chaos inside the bank even further. Then came the extraction of Raquel from the authorities which saw her dramatically re-enter the bank, while the Professor was simultaneously discovered by police officer Alicia Sierra. It’s not inconceivable to think that, given that we’ve seen two heists for each pair of seasons, the upcoming Money Heist season 5 will share the same format, perhaps focusing on a new heist, maybe even internationally. But that can’t be started until the loose ends of season 4 are tied up first. The show also loves to dabble in a non-linear approach to story-telling, so we could see Nairobi return much like Berlin’s character (in flashbacks) did in the later seasons after all.
