[X] Let Tala try and trick or sweet-talk them into leaving, letting you pick the nuts at your leisure.
The way I'm feeling this, Vashti would try to avoid violence (because violence is disturbing, she has rarely dealt it herself, and she is still shaken by the death of a strange and twisted spirit), and after her talk with Tala she would want to rely on the friend with whom she just bonded - likely too heavily, likely expecting too much of one who is just a girl in the monastery who talks to an imaginary parrot - and this is likely to fail. And failure will lead to the necessity of violence.
But this, in itself, is a valuable if sour lesson. Or so I think, anyway.
