He's an idiot. He knows he's an idiot but most importantly his girl knows. Except she doesn't sat it that way. She tells him he's got impulse control issues and "Noah you're amazing and one day you'll learn to better control your more destructive impulses" and blah blah. Point is she doesn't get super pissed when he does dumb shit.
Like the time he told Blaine about her dressing up as Princess Leia for him. Not white dress and cinnamon buns but gold bikini and chains Leia. Blaine's his boy and even tho he's into dudes doesn't mean they can't still share. As long as he doesn't give him too many details on Hummel rocking his world shit's kosher.
But now as he watches Berry stomp into the choir room he knows he's in for an epic Berry style rant. He's trying to remember if he forgot one of her crazy ass anniversary dates or if she knows he tossed JewFro into the dumpster today. What? Dude was totally preving on Puck's girl and Puckzilla does not appreciate it. She's all about "diplomatically resolving the situation Noah. Future Broadway stars cannot engage in fisticuffs." Yea he totally paid attention, mostly so she would shut down access to her goodies but whatevs. Crap there she goes...
"Noah, what have I told you about our private life?"
"Not to tell our friends about the ways you let me get at you..."
"That's not exactly how I phrased it, but yes. Stop describing our sex life to our friends!"
"Wait. How'd you know? And don't give me that psychic crap babe."
"Please, I wouldn't have to be psychic - and I am! - to know. Kurt looks traumatized. Santana looks turned on and licks her lips every time we make eye contact. Stop that right now Santana Consuelo Lopez!"
"How did she even know my middle name?"
"Now as I was saying, Finn keeps muttering about the mailman and won't look me in the eyes. Sam keeps asking how it's possible while Brittany keeps offering to demonstrate while mentioning plumbing and it not being cheating. The rest of them just keep giggling and Blaine Anderson if you think I can't see you high fiving Noah you are very wrong young man!"
"Baby you're always saying I need to communicate so I figured I'd start with Blaine. He's my boy! I know you told Beyonce about that time I cooked for you. It's not my fault Blaine can't keep his lips shut. Now how about we step into my office and I'll make it up to you."
"Noah what have I told you about trying to lure me into the janitor's closet. Furthermore..."
As Rachel's rant was cut off by the slamming of a closet door Sam could be heard asking "I still don't understand how she can bend that way!"
