You and your friend spend most of the time together for the rest of the journey. However, you soon realise that (s)he's also flirting with someone else.

How do you react?

    You don't mind; you can make it a triangle!
    You feel jealous and very angry with him/her so, when no one's looking at you, you push him/her overboard.
    You talk to him/her and say you are not interested anymore.
