[Raph]

Callum;

1. His friendship with Sam talking about girls, football etc.
2. His ongoing feelings for Charlie
3. His struggle with 'being a lad' versus 'being soppy, cheesy etc'.
4. Crying in the bathroom after his date with Charlie
5. Standing up for Sam when Jemima was harassing him.
6. Being one of the two people who didn't nominate Dexter in week 1 and hence showing lack of conformity.
7. Being supportive to everyone in the house, other than Sam.
8. His rivalry with Dexter
9. The psychologist task
10. His dance in the safe house
11. His striptease winning the house 100k
12. His epic win against Jackie Travers
13. Everyone bitching about him being 'too nice'
14. Callum nominating Dan in face-to-face noms
15. Callum's imitations of Dexter
16. Callum putting his all into every task and e.g. being the only one to take Wolfy's stuffed animal task seriously.

And honestly that's just a few; Callum was the greatest BBUK housemate ever.
