This quest is automatically acquired at the beginning of Act 2.
Speak to Aveline at the barracks in the Viscount's Keep. If her companion quest, The Way It Should Be, was completed, she warns Hawke that their new found wealth and influence has changed the fortunes of many people in Kirkwall; and not always for the better. When asked how she was settling into her new position as Guard Captain, Aveline complains that they are spread thin and how the templars are unwilling to requisition a few of their men to fight for the city guard as it was considered "demeaning". Even so, many of the guardsmen seem to have rallied under her leadership.
If her companion quest was not completed, she states that the previous captain left suddenly, and she now realizes why running the guard is so difficult. The viscount is weak and is unwilling to commit the resources she needs for the city guard. Not only because her position is only "interim", but also because he fears it would upset the templars. If Hawke encourages her to just leave the guard and work for them, she says that she knows the type of trouble Hawke gets into and that a casual relationship with them suits her just fine.
Aveline and Hawke part on either amiable or tense terms.
- Aveline: friendship (+10) if you say she loves the job.
- Aveline: rivalry (+10) if you ask her to quit the job.
The Ability to talk to her won't appear until you enter the Barracks. If you enter the Barracks, and leave without speaking the Aveline, then the ability to talk to her will disappear. You will have to run far enough away, then re-enter the Barracks. You might have to click on her twice in order for the cutscene to begin.
During the conversation, Hawke may say,"You guard the guardsmen!" which is very similar to the more famous Latin phrase Quis custodiet ipsos custodes? or "Who watches the watchmen?"
