The time rift has green circles that speed up or slow down characters in them. Though this is far from obvious if your natural response to circles on the ground is just to steer clear.
Also, it's not past Redcliffe, it's alternate Redcliffe.
I've been wondering about that, thanks. It really didn't seem any different than the others, but with a mage or ranged PC, it wouldn't. Even with a warrior or DWR, I'm usually using so many CCCs and AOEs, I'd likely miss it.
This isn't really a writing oversight, just a dialog quirk that piques my interest. Frequently, when you're talking to companions, a line of dialog will be followed by a sound from the start of the next line. Were lines of dialog dropped? What were they supposed to be? We may never know - what a horror! Or is it just that the voice actor gets a whole bunch of lines to read and they crop and paste the files into the game at the appropriate moments, and sometimes the edit isn't perfect, like a radio station playing the first notes of the next song on the record before the DJ chimes in and switches on the mic.
