Aveline Vallen/Approval

Friendship
Friendship with Aveline can generally be earned by doing what is lawful, but even more important to her is protection of the weak and acts of kindness. However, be aware that she also values family and friendship highly, and will occasionally favor bending the law or skirting what's right in order to support your companions (usually this means Isabela).

Aveline can be confusing in her alignment on the mage/templar issue. Her perspective is perhaps best understood as an affection for templars as people, rather than a wholehearted agreement with their philosophy. While she generally supports the Circle system and is wary of magic (particularly illegal magic), she believes the Gallows goes too far. She will thus appreciate when pro-Mage Hawkes try not to hurt templars, and disapprove when pro-Templar Hawkes are gratuitously cruel to mages or sell out more sympathetic templars to their hardline brethren.
