Barred Behind Doors - Odd Squad

Olive and Otto have been called back onto the Squad to cover for Otis and Olympia who are on a top secret mission. Instead of business as usual, Ms. O has assigned them an unusual case inside headquarters that begins to become more personal than expected.
If the tickling in Oscar's stomach wasn't butterflies, he didn't know what it could be. All he knew was that whenever Oona was around, the feeling was the strongest. Must be just a coincidence.
Ever since the first day of her employment, Oona had been feeling weird around Oscar; kind of a nervous, tickling sensation. She had passed it off as first day jitters, but as the days wore on, she began to have her suspicions.
For Ms. O, this outrageous agent activity is a violation of the second rule in the Odd Squad code of conduct. It needs to be dealt with swiftly and precisely, which is why she has employed her best former agents. Now she's doubting her decision.
