In the heat of the moment which was immediately after the selection ceremony had come to a close, the selected Thirteen gathered to recieve the blessings and order of the clergy and to formally meet with the new ordained Commander of the Holy knights.
Elizabeth, having watched the utter brutality of Amina, could no longer restrain herself from.soeaking her thoughts as she was at a loss as to why the clergy would allow a maniac like Amina join the ranks of the blessed Thirteen warriors.
This feeling of annoyance, caused her to call out Amina for being a heartless individual with a burning heart that could not control herself and thus ended up hurting her opponent more than was required.
The other inducted members of the Thirteen obviously had their reservations with Amina's personality but chose not to speak about it as they seemed it to be none of their business as long as it did not interfere with their work.
