The comments about Tea is Good. Though I found it to be very rude towards Reasoner too, but he was ok with it once everything was settled to that is fine. But you have to remember, not everyone plays D&D, not everyone plays, RPGs, not everyone knows how to form balanced character, not everyone is a native english speaker, etc. That situation could have been easily handled in a nice way, saying something a long the lines of you think Tea should add more backstory to her character, maybe change some of her skills because they seem too power/too weak, yadda yadda. It was over the line to just point it out with no positive feedback and suggestion.
