"Supergirl" Season 2 recently returned to the small screens with a winter premiere that featured Alex and Maggie re-confirming their relationship as a romantic couple. Aired on Jan. 23, Monday, the said episode titled "Supergirl Lives" showed Alex reassuring Maggie that she is committed to their relationship despite her initial worries.

In the upcoming Valentine episode of the CW series, the couple's relationship will be one of the focal story points. Episode spoilers posted on Entertainment Weekly teased of Alex's excitement over the annual hearts day and her eagerness in spending it with her new girlfriend.

However, Maggie will not share in the said DEO agent's enthusiasm about Valentine's Day. The situation will lead to the couple having their first major argument although the detective will try to salvage the situation by organizing a romantic event.
