The irony. And it is through that rejection that Salad awakens her Sharingan, and then uses Edo Tensi to resurrect Madara/Tobi/deadthings and BOOM. World War...what 7 now?
Boruto would give stop her from using Edo Tensei before she could even get the chance, then a fight between the two would break out! Just like what happened with Naruto and Sasuke the first time around, only this time Salad would lose badly due to Boruto's Byakugan and his presumed Bijuu powers that would kick her ass. In other words, rejection + an ass whooping by the guy she loves. Ouch! O.O
