So she had no problems to raid the Groove with them (and us).
This is what i liked about Dragon Age: Origins ...
There are some moments, where you can choose option that goes completely against some character moral codex, and they will turn on you. :3
I recall two situations ...
First when you choose to desecrate urn with sacred ashes ... Leiliana will turn on you.
Second when you choose to purge mage tower ... Wynne will turn on you.
Its so much better when companions are actualy willing to stand up for their values, and try to persuate you to reconcider, eventualy try to stop you ... than when they simply stand back there and silently disagree. -_-
Also it give better value to those options. :3
