trisha / trevi / tana

I’m not rly up to date with all of the trevi / trisha events. All i know is that Trisha was extremely inappropriate with Trevi. It’s odd to me how Tana is friends with both of them. Like how she got mad at Alissa for defending Nash. If Tana brought that energy to her close friends then wouldn’t she support Trevi and not associate with Trisha? What do y’all think?
