Under Coulson's orders, Jemma Simmons begins working under H.Y.D.R.A. as an undercover agent. While, Morse was assigned to also work undercover and to keep an eye on fellow undercover agent Jemma Simmons.
When Jemma Simmons' cover was exposed after she had made contact with S.H.I.E.L.D., Morse headed the investigation. To maintain her cover, Morse interrogated Simmons several times, noting her extensive background with S.H.I.E.L.D. She ensured that she intimidated Simmons as much as possible to test her loyalty to S.H.I.E.L.D.
However, Simmons cover was later exposed by Raina. So, Morse came to Simmons' aid as she fought two H.Y.D.R.A agents. Without much, time the pair ran through the facility while being chased down. Morse briefly explained that she was an Agent of S.H.I.E.L.D. working for Phil Coulson. As they continued their escape, Morse attempted to maintain her cover and distract Sunil Bakshi; when this failed the two jumped off the roof and escaped on a Quinjet piloted by Antoine Triplett. During these events, Jemma Simmons expresses her liking for Morse.
Back at the Playground, Jemma Simmons and Morse were greeted with warm welcomes, with Simmons noting to Coulson that Agent Morse was amazing, although Morse insisted that Simmons simply call her Bobbi.
Throughout the season, Jemma and Morse worked on various cases together as part of being in Coulson's Team.
After Bobbi Morse was introduced, Simmorse gained a medium amount of popularity in the fandom. It is one of the largest femslash ships in the fandom, along with Skimmons. Many fans adored their interaction at the start of Season 2. However, the interaction between Morse and Simmons became minimal throughout the rest of the season so less fans shipped Simmorse.
