(May go back and do the morning later, is inspiration strikes)
Telling Leonard.well, Sheldon has to tell Leonard
Next morning, Sheldon half swaggered, half stumbled into the apartment and slumped into his spot.
Leonard wandered out of his room in his robe, starts making coffee
"Morning Sheldon."
"Good Morning Leonard." He coughs theatrically "Leonard, as stipulated in section 8 of the roommate agreement I have important news to tell you regarding my relationship status."
Leonard stops messing with the cups and looks at him
"Relationship status? Do you even know what that means?"
"I'll admit i never really envisioned this part of the agreement as anything other than a way to keep a reign on your crazed libido, but as written it runs both ways"
Leonard sits up, looking at Sheldon with a puzzled frown.
"I am embarking on a romantic relationship with Penny and so duly notifying you as under Section 8 Subsection C. "
"Including paragraph 4?"
"Including paragraphs 3, 4 and 5."
"Wow. you're serious? You think she'd even say yes? I mean, no offence but you're... Sheldon.
she is way out of your league. "
"Is this because she is your ex girlfriend? "
"well, no. I'm just trying to let you down gently "
"I've already asked her to go out with me"
"What!?. wait! . if you've asked her and are now invoking section C. She said yes?!"
Sheldon smiles smugly "Indeed she did"
Leonard looks at him astonished "Did you even come home last night?"
Sheldon stretches his arms over his head and grins his smuggest grin
