The 2nd time, Esbern was with us, and I picked "we should all travel together". After about 5 minutes, they all of a sudden stop following me, then they say "We'll meet you at Karthspire". I was like "fair enough, I'll just follow you then". We get to Rorikstead, and all of a sudden, she turns around and walks in the direction that we came from, and then after about 5 minutes, turns around AGAIN and walks in the direction we were originally going in (with Esbern following behind her).
This went on for 10 minutes (walking back and forth between the same points) before I just said "You know what, [censored] it. I'm gonna get there myself cos this is a total waste of time. I'll let that dumb bish sort herself out".
