All I want in this track is for Sona to directly tell Dev about Sanjana's veiled threat to her on the phone and her behaviour with her in the office. Casually say "some girl stopped me and asked if I had an appointment to meet you." Even if Dev says oh she's the new hire, Sona can point out that it's Tina's (or whoever) job to check your appointments.
I just know this won't come up and all I want to see is Devakshi communicating more than just "I love you".
