According to Taena of Myr, Ser Tallad desired Alla or her cousin Elinor. When Queen Cersei conspired to have Margaery implicated in extra marital relations she made the Blue Bard confess that Alla had only watched Margaery and her cousins have sex with a lot of men but did not participate and tried to persuade Margaery to stop. Cersei thought that this would make the confession more believable. Taena would then try to persuade Alla to confess and bear witness against Queen Margaery and their cousins. Cersei then had Margaery and her cousins (among them, Alla) imprisoned by the Faith.
