Debbie is a hot kettle.
Having the biggest frontal lobes can really set you apart. Just ask Debbie, the hot-headed, know-it-all, Brains Tribe member who continued to rub everyone the wrong way in Week 2.
Both Peter and Liz noticed how, although Debbie talked a lot, she didn't really exhibit any real strategy; however, according to Peter, maybe "a Brain that has no game" could actually be good company to keep.
Unfortunately, Liz didn't feel the same way. After Debbie criticized her for the way she boiled and filtrated water, Liz grew even less fond of the chemist and a divide started to form between the two.
