Knowing that the scene where Alex and Kara reunite was also the first scene with Chyler Leigh and Melissa Benoist since March of last year, makes it all the more emotional.
Although the episode ended right when the Danvers sisters reunited, it was still as emotional as ever.
Throughout the first half of the season, Alex had been desperate to reunite with her sister once again, completely worried about Kara.
Since Benoist went back to filming later than everyone else due to her giving birth, the reunion was more special for her and Leigh.
