My 2 cents: She definitely seeks attention for her illness - a red flag. She constantly turns conversations towards her illness. She limps markedly when people are present (from stitches in her foot), but not when people are absent. She tells HGs that she's terminal, but also wants to freeze her eggs. She claims to be $200,000 in debt, yet has opened 2 dance studios and recently bought a brand new car. She claims her disease is genetic, terminal, and makes her infertile. She also claims her mom has the same disease, but... her mom is in her 50s and has multiple children.
