Alright, I could have read the post a bit better, and I apologize. As for how to proceed? Well, you've got a couple options. One, Serene could be focusing on guarding Ana, hence you could protect her from stray attacks that head that way, or (and this is to make it up to you more than anything) you can go ahead and post Serene making into the castle to fight alongside Jared and Elsa. Or you could, should you dare, enter the Shrine of the Silver Monkey. The choices are yours and yours alone. Good luck.
