I've got two main characters... Cora - who walks dogs -, and Gregory - who works in a science lab.
1) What's your character's favourite colour?
Cora's is orange, and Gregory's is a tie between blue and green.
2) What was your character's most embarassing moment ever?
Cora's would be when she accidentally blurted out that she and Greg (who she's secretly crushing on... lol) should move in together while they were on the run, since at that point they were just good friends.
... Greg, on the other hand, has had a lot of embarrassing moments in his life.
3) Does your character prefer sandy or stony beaches?
Cora like's sandy beaches, and Greg doesn't really like beaches, period, since he can't swim.
4) What would your character put on a pizza?
Cora like's vegetarian, while Greg likes ground beef and onions.
5) What is/was their favourite subject in school?
Lunch for Cora, and science/chemistry for Greg.
6) What is your character's deepest fear?
For Cora its heights, and for Greg it's water.
7) What is your character's favourite book?
Cora doesn't really like to read, but the last book she read was from the Twilight series. Its not her favourite, but its something. XD And Greg... he reads comics, if that counts.
8) Can they swim?
They both can't.
9) Are they allergic to anything?
Cora is, to pollen. Greg isn't really allergic to anything. Well, except cats.
10) Does your character have any piercings/tattoos? If not, would they like any?
Cora doesn't like needles, so she doesn't have either, while Greg just doesn't see the point of them.
