Via the power fluctations near the end of June... Xion absorbs memories of others - though most of the time it only latches on Sora or Roxas (or as Mala and I have both assumed, her AU self).
It's not something she can control, rather part of the programming she was made with, though it's something that could probably be affected by the collars. Would it be reasonable, you think, that if her powers in general were to go out of control, this property of hers might too? And in particular, it might absorb some memories that aren't Sora's, Roxas' or AUXion's? This has happened in canon - in one instance where she pulled a memory from Riku, as seen in this scene (and Roxas gets caught up in the equation IDEK this scene is so confusing I'm not sure if anyone's been able to figure it out).
