So when R2 and 3P0 were spoiled, I, as well as many others played 3P0 as an optional attachment. Some people claimed that based on his wording that he was in fact not optional. But no, we said, his counterpart text simply meant if you added him to your army, he must be added to R2.....right?
Well take a look at Iden's droid counterpart. Its text is different than 3P0s. So is goldenrod in fact not optional???
