Gansa told Deadline, "I think first and foremost you have to look at the Peter Quinn-Carrie Mathison relationship. That was the first dramatic scene of this season, Carrie and Quinn together in that VA hospital. In large part, that has functioned as the emotional center of Season 6."

"One can expect that that relationship is going to come to some head in the finale, because that was the first and foremost idea we came into this season with — so there's that on the table," he added of this Sunday's finale.

The season 6 premiered with Quinn, recovering from both psychological and physical trauma, following his near-fatal brush with death in season 5 finale and he was seen blaming Carrie for his current condition.

The showrunner also spoke about what fans can take away from the episode. "I hope they feel one thing more than all, and that is, I want to see next season. That's the purpose of the finale. We really hope that this year's finale sets up the final progression of this series."

The finale will evoke a shocked emotion said the creator and added, "That is, Seasons 7 and 8, which we hope to tell as one story, and the finale of this season really hopefully tease that up. Shocked is always a good emotion to evoke as well, so I guess I would hope they would be shocked as well."
