#3 The loss to Almas forces him out of retirement and into a feud with Ciampa
Not only could he be forced to leave NXT if he loses to Almas, Gargano could be berated in the process. Perhaps Gargano loses the match to Almas because of a distraction by a returning Tomasso Ciampa, and after the match we could see Gargano once again beaten down, or perhaps see Candice Lerae harmed in the process of trying to stand over her beaten husband, leading a now-retired Gargano into a whole new mindset.
Much like a father out to exact revenge on anyone that harms his children, he would be a husband out to defend his wife. Ciampa could address the incident with General Manager William Regal, resulting in a revocation of the clause that Gargano had to leave NXT. Regal could easily empathize with Gargano's plight as a husband, how he would not rest at anything to ensure his revenge. It would be Johnny Gargano like we hadn't seen him before.
