The Legend of Korra! I decided to get back into it since the start of season 3 came about. I attempted to watch season 3 but could not understand anything from the previous episodes, and therefore i decided to get into season 2 and finish it in time to begin season 3!
So briefly… *spoiler alert* This episodes heads into the harmonic convergence and Unalaq is attempting to fuse with Vatu, the dark spirit who is still encaged in the tree of time. Yup shit goes down the the harmonic convergence happens… now onto the next episode!
p.s. if you felt like season 2 was slow… well it is. So just get through the first couple episodes and it should definitely pick up no doubt.
