I entered the instance for the Story Quest “Stealing Secrets,” ran/used Infiltrator’s Arrow once to talk to Tybalt, and skipped the dialogue. Afterwards, when I spoke to Riel, when the cutscene played, there was no audio with it. Instead, my character (level 46 Human female Thief) said a word or two, and I randomly heard Tybalt’s line, “Keep your voice down, initiate, and pretend that you’re buying some apples!” (or something like that). Also, my character’s name and Tybalt’s name would appear in the black windowed area at the bottom of the screen below the cutscene, probably to indicate when we were speaking in the previous dialogue sequence, and it seemed to follow scene swaps during the cutscene, but that could have been coincidence. Anyways, that’s it.
