## Relationships

### Susan Test (Brother sister)

**Mary** and **Susan** have a wonderful sisterly relationship. As twins, Mary can often read Susan's mind (like "twin telepathy"), but it is common that they're both geniuses. Working at the lab all day long can make Mary and Susan fully exhausted, and so they don't need the energy to help **Johnny** with his issues. Also, Mary and Susan do almost anything together, like staring at **Gil** (their biggest crush), or supervising new experiments in their lab. However, despite their relationship, for some reasons, they can bicker when it comes to their differences.
