Abbott Elementary season 4 wasn't on last week on Feb. 19, and we definitely felt the comedy's absence on our Wednesday night. But the good news is that the sitcom is back tonight with a new episode for us to enjoy! So what are all the tune in details and what are our favorite teachers up to this week? Read on below for the details.

It's the 100th Day of School at Abbott Elementary
Many schools like to commemorate 100 days of each academic year as an important milestone for those in younger grades. It's a way to signify the young students' achievements and have a bit of fun celebrating all they've learned so far. Some schools will throw parties, make T-shirts, or do other activities to mark the occasion.
Obviously with Abbott Elementary season 4 episode 15 being titled "100th Day of School," that does mean that the new episode will be focused on this aspect. Based on the featured image above, one way the school is taking part in the festivities is by taking photos of the students. That's adorable!
The synopsis also tells us that, Barbara's daughter Taylor is arranging a surprise for her mom as part of the celebrations taking place at Abbott. There's also the fact that Melissa, Jacob, and Mr. Johnson conduct a search party. Huh. What could these three be up to?

I'm curious about what Janine and Gregory will be doing for their respective classes since they're not mentioned in the description. Plus, the two reached an exciting milestone in the previous episode where they told each other 'I love you.' Aw!
That scene gave me all the feels, you guys. I can't wait to see these two lovebirds on my screen again tonight. And speaking of the love department, can we finally see some progress being made between Ava and O'Shon? I'm already shipping it so hard! Check out some more first-look images from the episode below.
