@FreaknSweetAmy ; Known bug. Hit [Esc] after Lady Harriman appears and you get the 'Loading' icon. You miss one snippet of dialogue, but can continue the quest.

There may be a freeze at a later point in Sebastian's questline that can't be skipped with the escape key.
If I recall correctly, the bug is triggered by having the Sebastian DLC and Legacy both installed. The workaround is to install Mark of the Assassin as well, but that's not a great solution if you haven't already bought it.
You can also shuffle some files around while playing Sebastian's quests. Here's how: https://answers.ea.com/t5/Dragon-Age-2/Freezing-issue-in-The-Exiled-Prince/m-p/1413440#M1862
