Sometimes Tully gets strangely clingy and meek, at which point he’ll attach himself to the nearest companion and not be deterred until he gets a straight answer. Solas and Cassandra, his main victims, have long gotten used to it, and between the two of them have likened it to a large cat wanting affection deciding to drape itself over you until reassured.
