I bet Glinda, the witch of the north and witch of the east, were so close enough that they considered each other sisters. However, Glinda (I bet) was the only one who wanted to let Zelena in while the other 2 were a bit skeptical of her nature. When Zelena betrayed Glinda, they (The witch of the North and East) voted to have Glinda forever removed from Oz. That is probably why Glinda hides out in the Enchanted Forest, and only allows those pure of heart to enter, so she never has to deal with people like Zelena, that have potential but end up choosing darkness.
