Saam tends to have a lot of built up bitterness that can come out when they lose their patience with someone. Once that reservoir of patience is shorted, Saam has no problem using rather cutting words to get their point across even if it does end up involving previous resent feelings they had carried with them from time to time. 

It’s easy for them to be sour and yet happy for others at the same time. It’s a reflection on their own exhausted and outdone nature towards everything they had been through and how much they feel cheated out of.
