Varric Tethras/Approval (Dragon Age II)

Friendship
Varric likes to talk and likes Hawkes who do, too. Solving problems and gaining advantage through diplomacy, outright lies, and even blackmail will impress him, while straightforward violence and thuggery leaves him cold. He also responds well to joking, flirting and sarcasm and to mild greed. Beneath his silver tongue, however, he's a goodhearted person and will appreciate Hawkes who look out for their families and are kind to dwarves.
