Forum:Isabela-Joss Whedon reference

While questing with Isabela in my party, there is a side conversation where she says "Abominations go Grr Argh." Definitely a reference to the sound associated with Joss Whedon's production company Mutant Enemy, which he created to produce "Buffy the Vampire Slayer." Happened to me in Act 2, but don't know if it is restricted to that.
