Need Some consigli

Lyrical seems to be in a predicament. Her high school BFF, Topaz, and her pre school BFF, JeMmela, are arguing. Aparently, Topaz seems to tease JeMmela alot. JeMmela tells her brother, who is Topaz's boyfriend, about it. He then tells Topaz and now she is upset. All of that is affecting Lyrical and she has no idea what to do. Any advice?
