It's been a long time coming. 12 years after the Friends finale, NBC is finally airing a reunion episode on 21 February. As part of a tribute to veteran sitcom director James Burrows, the two-hour special will reunite Jennifer Aniston, Courteney Cox, Lisa Kudrow, Matt LeBlanc, Matthew Perry and David Schwimmer.

There's a catch though — NBC chief Robert Greenblatt has hinted that they might not actually get all six friends in the same room, for logistic reasons. While they've been on screen a few times before, all six haven't been seen together. Perry, Aniston and Kudrow have starred in guest spots on Cox's show Cougar Town, as well as appearing as themselves on talk shows with Ellen DeGeneres and Jimmy Kimmel. Of course, more than a decade on, the stars are set in their respective schedules: 'Chandler' will have his playwriting debut The End of Longing on the West End, while 'Rachel' is in talks to produce and star in The Yellow Birds, a movie based on the award-winning book of the same name.

Friends ran between 1994 and 2004, producing quality pop culture nuggets, hair trends and a fantasy that six friends could successfully sustain a tight friendship beyond their thirties. Ross and Rachel's child Emma would have been 15, while Ross's son Ben would be 21. As for the main cast? Here's what we want to see.

1. The one where Ben comes out.

Splitting his time with lesbian mothers Carol and Susan and Ross and Rachel, Ross' 21-year-old son has probably grown up with a healthy set of mommy and daddy issues. Fresh out of college — with a degree in paleontology, perhaps? — he returns to Manhattan with a boyfriend in tow.

2. The one where Chandler and Monica are on a break.

It was Ross and Rachel for so long, with the whole will-they-or-won't-they and we-were-on-a-break business. It's time for marital blues to hit The Chan Chan Man and Harmonica, and we reckon it's just as the twins leave for camp and the parents find themselves left alone for the first time. Well into their late 40s by now, Chandler's jokes are starting to get really old, while Monica's OCD has pretty much taken over her life.

3. The one with the birds and the bees.

It's Emma's first period, and Ross doesn't quite know how to deal with it. While Rachel's away on fashion week duties in Paris (the cast can't all be together, remember?), Ross wakes up to a terrified Emma not knowing what to do with her entry into womanhood. Aunt Monica tries to help, albeit unsuccessfully — her OCD gets the better of her when cleanliness is in question.

4. The one with the big Hollywood premiere.

Since proving herself to be so convincing as Joey's agent Estelle, Phoebe finally makes a career switch from being a masseuse to Joey's agent. After successfully booking him into a Days of Our Lives movie, the duo attend the premiere only to be stalked and harrassed by a persistent reporter — who's none other than Janice. Oh, my, God.

5. The one where they all have a midlife crisis.

The six now find themselves with grown children, senior positions in their careers, and well, more things to worry about, health-wise. Following each friend as he or she realises that half of their lives have gone past, we'll watch as Rachel tries to go back to The Rachel haircut, Phoebe reunites with David the Scientist and Chandler hooks up with Janice. Whatever happens, we'll still be there for them.
