I wonder if the person in the pod is there to help the people of Kara's Earth adjust to the merging, season 2 for Supergirl is said to focus on the past and if this character was a version of Kara, weather by name or past, who simply never became a hero then it could be focusing on how different their timelines are. It makes sense though, the frequencies were forshadowed to be simmilar and as Kara said, "Two Earths with simmilar frequencies can merge." And Barry's constant time/interdimensional travel is likely messing with the wall keeping the two apart.
