In the previous episode titled "The Singularity," fans were delighted to find out that Fitz (Iain de Caestecker) and Simmons (Elizabeth Henstridge) had finally decided to take their relationship to the next level after years of friendship. However, the viewers are also looking forward to find out how long it will work for them.

As reported by Entertainment Weekly, executive producers Jed Whedon and Maurissa Tancharoen teased about the Fitz-Simmons relationship and how it would progress.

In an email to the website, they said: "We want their relationship to feel like their friendship did, because all the best relationships are just that. So moving forward, while this change in their friendship would hopefully only deepen their connection, it is bound also to make things a bit more complicated."
