We don't see her around Ash, Bonnie or Clemont in the first two episodes (except that small scene with Bonnie and Fennekin which takes place in God knows what episode). She's also not present in the Dedenne episode (which I assume is the third episode of XY anime) nor in the scene where Ash, Bonnie and Clemont are chased by the angry Beedrill. She's not the part of the group yet.
We know that Ash heads towards Santalune and Serena is STILL not a part of their group. We saw Ash battle
I went from hearing Serena say Pokemon Master (during the livestream) and being excited (because someone else heard her say Master too), to actually watching the preview and hearing her say Morana, to which I was somewhat disappointed because it wasn't Master and then someone who actually knows Japanese cleared things up by saying she simply said she was going to get her Pokémon. @FANG-TAN; :P
And now we still have no clue on her goal.
The best part is, some silly-billies are taking this seriously and going crazy LOL
