[SPOILERS for those not caught up on Supergirl ahead.]

-

Many fans are excited for next week's Supergirl because it will introduce The CW's three-hour DCEU crossover event, "Invasion!" Next week's episode, titled "Medusa", will not focus on characters from Earth-1, however. Though Cisco and The Flash will make an appearance toward the end of s2E8, it mainly focuses on developing the ongoing Supergirl plot.

The current most pressing issues over on Supergirl's earth include Alex's internal struggle with her evolving identity, James and Winn's secret teamwork on Guardian, and a reincarnated robo-Hank Henshaw called Cyborg Superman. It looks like Hank will continue to antagonize Kara and her friends next week, according to a sneak peek at the upcoming episode and its corresponding synopsis.

The synopsis for "Medusa," according to Television Promos, is as follows:

Eliza (guest star Helen Slater) comes to town to celebrate Thanksgiving with her daughters. Alex (Chyler Leigh) decides it’s time to come out to her mother; Kara (Melisa Benoist) is shocked when Eliza suggests Mon-El (Chris Wood) has feelings for her, and Winn (Jeremy Jordan) and James (Mehcad Brooks) consider telling Kara the truth about the Guardian. Meanwhile, CADMUS unleashes a virus that instantly kills any alien in the vicinity so Kara enlists an unexpected ally – Lena Luthor (Katie McGrath). The epic superhero crossover kicks off tonight when Barry Allen (guest star Grant Gustin) and Cisco Ramon (guest star Carlos Valdes) seek Kara’s help with an alien invasion on their Earth.

You can preview the episode, featuring a Mon-El/Cyborg Superman fight scene and an attack on the alien bar, above.

This definitely doesn't look like it's going to be an easy week for Kara and her crew. We're especially eager to know why Cyborg Superman felt the need to attack the alien bar, and if the effects of that smoke bomb were permanent, so it's nice that we won't have to wait long to figure it out. Of course, there are a lot of bigger questions about Cyborg Superman that the series has yet to answer; namely, where did he come from, and why?

It'll be exciting to see how some of Supergirl's current issues, from the personal to the practical, develop next week. We already got a glimpse at some of those developments in a special Thanksgiving clip, but we hope that the interruption featured there -- likely Cisco and The Flash -- doesn't signal the end of both Guardian and Alex's chances to share their secrets.

It's shaping up to be an enthralling week coming up on The CW, and, as usual, Supergirl will kick things off on Monday night. From robo-enemies to otherworldly visitors, it looks like the beloved series is preparing to deliver another hour of entertainment and action to fans.
