Two Minutes
To be honest, I couldn't do any story ideas in two minutes. With the more complicated stories I tried to spend some time setting up the meeting with all the background and then counting two minutes once the characters were actually face to face. Even then the face to face time is probably more like five or ten minutes.
I figure, if they were going to do the scene in two minutes it would have to go like this:
Blaine happens upon David and Sebastian together somewhere, doing something. Hellos are exchanged. Sebastian says something stupid or insulting to Blaine. Dave explains why or what Seb and he are doing together as friends and/or boyfriends, showing that Sebastian is staying true to his word and trying to be good. Dave says he's wonderful now and his life is full of promise. Kurt's name comes up and is most likely still in contact in some way with Dave. Sebastian says something insulting about Kurt. They all leave as friends. See even that sketchy scene was probably more than two minutes. Anyways, here is my first idea about what could have happened...
Story I
(What Ryan Murphy most likely had planned.)
"Hi Dave. Hi Sebastian. This is a bit of a surprise!" Blaine said and that was certainly an understatement.
"What exactly is the surprise? That we drink coffee like every other human on the planet or that we'd be seen in public at The Lima Bean, a poor excuse for a chique cafe who allows loser McKinley Glee members to mix in with regular patrons?"
"Seb be nice." Dave warns. "I think he's surprised to see us together."
"Is it really such a surprise? I was really sorry for my part in Dave's drastic decision to kill himself and I dedicated the Warbler's song 'Stand' to him at Regionals. Why wouldn't I extend friendship to him when other people I could name, didn't?"
"If that's a dig at Kurt, that's not fair. He's in New York and working hard to build his career. He is extremely busy; why he hardly can find time for me and I'm his fiancé. "
"Oops! I think I hit a sore spot!" Seb said and smiled maliciously.
"I thought you turned over a new leaf? Where is that kinder more compassionate Smythe we were supposed to see?" Blaine fired back.
"He is kinder and nicer. He's helped me a lot. In fact, we're in here to grab a coffee before we go to an LGBT youth meeting. I going to be speaking about my experiences coming out and Seb here is coming along to support me." Dave explained.
"That's amazing Dave! I have to get to Glee practise, otherwise I'd join you." That comment was met with a scowl from Sebastian.
"Even though Kurt isn't touch as much as he'd like, I know he will be pleased that you doing so well." Blaine continued sincerely.
"Tell him I'm in a really good place. And tell him how much I appreciated all he has done for me. Let him know how great a friend Seb has been to me and that I feel safe and secure with him around." As he said that, he threw his arm around Sebastian's shoulder and gave him a sideways hug. Blaine could see that the Warbler was so pleased and proud he could burst.
"I'm happy to do it Dave." Sebastian said with a thick emotional voice. He cleared his throat to get rid of the feelings and finished with a classic dig. "I'll stick right by you. Not like some."
"Seb." Dave said in a cautioning voice. A look passed between the two that was very interesting. It was as if there was no one else in the world except those two.
"It was great seeing you both, but if I don't go now I'll miss my practise. See you later" Blaine finished. He waved and set off out the door.
"Not if we see you first!" Sebastian called out as a last parting shot.
Blaine smiled and shook his head. He fumbled around for his phone and quickly called a familiar number.
"Hey Kurt, you'll never guess who I ran into... Dave Karofsky and Sebastian Smythe... No, together at Lima Bean...I'm not sure if they're together, together but if they're not, they soon will be, judging by the looks they exchanged...Don't worry Kurt, he is really, really happy and Seb - I am think he's in love!"
