I'd rather have it the other way round, with her being betrayed by Alvarez.

Like for example Brandish voicing her intent to try to change Zeref's mind about his war and one or more of her fellow Spriggans seeing this as treason and attack her.

And either she manages to retreat or is saved/supported by FT. Though I think they should form an alliance rather than Brandish actually joining the guild.
