This show has never rocked the boat formula-wise. It has always been about Erica learning and growing. That isn't going to change now that she's a therapist in training. Personally, I feel that it is a good thing that Erica she does not rely on time travel to help her friends because show the audience that anyone can do it too - help their own friends and family.
You could see a little progress though with Erica's learning process. I'm also surprised and disappointed that Sam is pregnant. I thought that such a storyline would have been better for Jenny, who I predicted would show up pregnant.
