yes those messy first boots
any alliance prediction from me: Samira and Fleur not bc of colour don't worry but i see 2 feisty strong power women in them, i can see them teaming up for that reason
can see Shereen going both ways, either going far as journey contestant, or flopping under the pressure
Harry Reid looks like first boot material

however maybe if he's any physically weak might also be an advantage if his personality is any good (i know this out of experience via expeditie robinson here, some of physically weaker stay in longer than you'd expect)
Louis might be seen as too competitive, that is a disadvantage in shows like this if not strategically careful enough could be a shock boot or if he plays game smart he can go all the way
