John-

John can be a bit negative, but you create more of an optimistic streak in him, or "realist" as he likes to call it

Paul-

Paul's a perfectionist. He usually is tressed about albums or shows, but with you, he's relaxed a bit

George-

You helped him to open up. To not be so shy. He's more talkative and likes to get to know others

Ringo-

You help him to focus more, and to feel proud of himself.
