the song referenced is "Daylight" by Matt and Kim, which was used in the show a couple of times
Her first day of the internship just so happens to fall on her third day living in Washington. By this point, she pretty much trusts her roommate to not steal her stuff while she's away for the day, but she still takes her laptop and phone with her to work, just in case.
It's the bus first, then the train, then a 15-minute walk. She memorised the route as soon as she found out she'd got the internship.
(Well, maybe not as soon as, there were other things to think about. One other thing to think about, at least.)
She drafts and then redrafts a quick text to the group - they have a group chat going on, newly founded by Britta, and although she hasn't been using it too much recently, it's nice to see what's going on. "First day of internship today!"
It's before 7am when she sends it and of course she doesn't expect anyone to have read it, that would be ridiculous, it's 5am over there - and so it takes her by surprise when her phone dings and shows that the message has been read.
A short moment later and the three little dots pop up. They stay for probably an entire minute, and as she watches, she tries to tamp down her expectations a little. It can't be him, it's probably Abed or maybe even Shirley (what's the time difference there, again?) But then they disappear.
Okay. That's okay. It's whatever.
She drops her phone in her pocket and triple-checks that she's got her keys and binder and handbook and laptop and money and everything else she possibly could have any small need for in the 8 hours she'll be spending there.
The bus ride is actually pretty pleasant. The only other people on at this time in the morning are a few elderly people, most of whom shoot her a polite smile as she makes her way through the rows of seats to the double-seater in the back.
She plugs in her earphones and stares out the window, trying to focus on the early-morning scenery whizzing past. A few more people get on at each stop, and it's, well, nice. To watch the city waking up; seeing snippets of middle-aged suburban mothers kissing their children goodbye, and fathers dressed in shirt-and-ties collecting the morning newspapers.
Her phone suddenly chimes, abruptly interrupting the song lyrics - "and in the daylight we could-" signalling a message in the study group chat.
"knock 'em dead"
It's from Jeff. It'sfromJeffit'sfromJeffit'sfromJeff.
(He's probably just replying so the notification will disappear from his phone.
But maybe?
Maybe this is a sign?)
The rest of the group's well-wishes start to flood in around her morning coffee break. Abed and Troy urge her to attempt to infiltrate the FBI database, Shirley tells her to "have fun!", Britta sends her a nice "good luck!" message, with a string of unmatched emojis. Frankie adds a polite "this is an excellent opportunity for you" soon after lunch.
That day is a good day.
