Seeing Videos and Clips is different. Elliack was saying he/she could tell what was happening from the poor writing which I find it unbelievable.
And as for the person saying Savage is going to kill Galia? We knew she was going to die but how did you know it was Savage and Not Maul or any of the Mandalorians that would kill her?
Oh I'm a male :P
Yes, the videos, etc helped; but I could predict most of the obvious factors because of said writing yes.
Doesn't take any skill to see what will happen when a crapload of foreshadowing and "redshirt" elements are in play.
