A/N: After so many requests for it… here's the characters' reactions to Jack! With a little bonus of Jack's reaction to them.
Jack Harkness: If the Doctor, Amy, Rory, and River are all confronted with Jack, things get complicated.
*For example, if each of the four met Jack at a bar…
1. Amy would be happy to get hit only, not realizing that's how Jack treats everyone. ("Oh, well then… what were you saying about being a time agent?")
2. Rory would be highly disturbed by the man. ("Er… what? You did what to the Doctor?")
3. The Doctor would probably run to the bathroom to hide. ("I… have to pee. For the next… how long are you staying here?")
4. River would start competing with who kicks more butt. ("Oh, you asked for it.")
*Another example, if each of the four had to spend a day with Jack…
1. Amy would quickly tire of the annoying man. ("Go find someone else to play with.")
2. Rory would probably rather wait another 2000 years than spend the day with Jack. ("Please, I swear to you I'm not gay!")
3. The Doctor would be constantly making sure he didn't get sexually assaulted. ("No! I said no! … Bad boy, Jack!")
4. River would either kill Jack or end up dead. These two together are a bad combination. ("Bang!")
-In short, the four time travelers all have different reactions when dealing with Jack. Some are alright with him, some are afraid, some try to avoid him, and some should never ever meet him.
**What Jack would do to each of the four…
1. Amy- Flirt ("Mm, ginger.")
2. Rory- Flirt ("Tasty. You single?") (Rory- "No.") (Jack- "I'll pretend that was a yes.")
3. The Doctor- Flirt ("You may wear a bow tie now, but I'll never stop trying!")
4. River- Flirt ("She could kick anything's butt. Now THAT's my kinda woman.")
I'm sensing a pattern… Jack Harkness- anything that moves.
