Ok Patrick Weekes, WTF. You're a talented writer, but your some of your answers in this interview fly in the face of events in the game.
1) They didn't want to have the qunari in Trespasser be "the offshoot of an offshoot of an offshoot". But that's what we end up fighting; the Viddasala is either acting against the orders of or without the knowledge of the Triumvirate. She's mining lyrium for her saarebases without permission, and is eventually disavowed. The game goes out of it's way to make it clear she's off the reservation, which is why it's BS that Iron Bull listens to her anyway.
What are you talking about? Patrick Weekes has simply confirmed in this interview what has been strongly implied in Trespasser itself - that was not any sort of offshoot, but a super-secret and fully sanctioned Qunari operation.
....You really think that the Qunandar would allow Viddasala occupy their only source of lyrium if they didn't know she was turning Sareebas into super-soldiers? You think that epilogue slides would mention that the Qunari plan of sneakily invading the South was thwarted and hence they turned to Tevinter if the Qunai leadership didn't know about it?
Vidassala's been disavowed only because Solas messed up their plan by making Inquisition aware of it and enabled Inquisitor to go after the qunari.
2) Mother Giselle is supposed to be a counter-point to the trivialisation of religious belief. WTH? The same character that tells you to continue to claim a false divine mandate after Adamant? In a game with both Cassandra and Leliana, Giselle is unnecessary and is in fact the exact sort of character Patrick Weekes says he dislikes. To her the truth of the Maker is less important than the good works that can be done in his name.
Er, no, she doesn't tell Inquisitor anything that is even close to "continuing to claim a false mandate"
We can have a full conversation with her about it, that is mostly about metaphors and interpreting everything that happens as evidence of Maker's subtle actions (and as flawed as her thinking I personally think it is, it's very realistic, considering that I know very smart, compassionate people who believe the exact way she does).
