MEMBER'S CHOICE - "Here’s the thing Jim, sometimes being in love means doing things you don’t want to do for the other person. For you, right now, it means just being her friend. And I think you’re selling yourself short, you are strong enough to do this."

Over a year after Casino Night, Jim is really happy with Karen. But when Pam finally confesses her feelings to Jim, is it too late for them?

"It seems odd, in the ironic, slap-in-the-face kind of way that since her incident, it’s been easier to let him go."

Something bad happens to Pam. Very Dark.

After a fire destroys her apartment, Pam moves in with Jim and Karen. Everyone has to find out how they define "friendship". Not for those who prefer their Jim to be wholesome.

MEMBER'S CHOICE - An alternate universe where Pam and Roy had a wedding, Pam goes to art school in New York, Dwight owns a restaurant and Jim works for a job in advertising that he likes a lot more and gets a lot more money at.
Basically? Dunder Mifflin never exists. And everyone meets under different circumstances.

The characters are pretty much the same -- personality-wise -- they just have different roles and work different jobs.

Jim and Pam’s four First Kisses…and first Last Kiss.  Spoilers through "The Job," unspoiled spec thereafter.
