Thor, Vol. 1

Thor and Sif return to Chicago, where Sif tries several times to tell Thor she wants to return to Asgard, but they are continually interrupted; first by Captain Ultra and then a medical emergency. They then go to New York to attend the wedding of Jane Foster and Keith Kincaid. Immediately afterwards, Sif tells Thor she's leaving and does so. She arrives in Asgard and tells Frigga what is troubling her. Frigga tells her that Odin himself has been waiting forever for Thor to give up Midgard.
