Kara's childhood in Earth-Prime is not and cannot be the childhood she experienced in Earth-38. However, it is the childhood Alex experienced. Unless it isn't, because J'onn's space magic could somehow "restore" memories that were never there in her mind to begin with.

Yeah, if you think about to much, you'll get a headache and which Alex's childhood is the correct one for Earth Prime?

In Elseworlds we did have a Earth-1 Alex. The new Earth-Prime is a composite of various Earths, including both Earth-1 and Earth-38, which each had an Alex. I think any continuity issues between Supergirl pre-Crisis and Supergirl post-Crisis can be dismissed due to the circumstances that created the new Earth Prime reality.

Well, thank you both for clearing that up but you lost me at the grocery store.

Just hang a right on aisle 2 and follow the signs.

The writers' worrying about timeline continuity is probably very minimal. Look at how many times they've changed how long Kara's been on Earth. Their grasp on their own continuity was tenuous, at best, before Crisis. Post Crisis? Kara's past in the history of "Earth Prime" is completely up in the air.

It is what it is.

In Earth-38 "Midvale," Cat Grant is already established enough to have memoir, Nine Lives and Counting. Now, Earth Prime's "Prom" episodes, set after that, have her still establishing herself as "CJ."

Kara's childhood in Earth-Prime is not and cannot be the childhood she experienced in Earth-38. However, it is the childhood Alex experienced. Unless it isn't, because J'onn's space magic could somehow "restore" memories that were never there in her mind to begin with.

Earth-38 Lex Luthor is a supervillain. Earth Prime Lex was always looked on as a hero.

The number of differences between the memories of Earth-38 people and Earth Prime people would be staggering. Barry, Kara, and the others would at times be tripped up by events that never happened or happened very differently involving their respective Earth Prime counterparts before they "woke up" in the timeline. They effectively inherited the past decisions of their dopplegangers. (What happened to those original Earth-Prime versions of the paragons, by they way? Were they simply obliterated so the Earth-1 and Earth-38 versions could continue, trapped in a world they never made? Seems harsh.)

It all falls apart when subjected to any kind of analysis. With Supergirl in particular, timelines and history are pretty much meaningless.

It's a shame that price we pay for following the show is literally abandoning any sense of continuity, but that's where we are.

Repeat to yourself, "It's just a show. I should really just relax."

One other thing I wonder is that the synopsis states that this will be the first time that Kara experiences Kryptonite which will be interesting to see - however she probably just feels the effect without seeing the mineral or she may even see the mineral but just does not know what is - so, Brainy and Nia would need to remember not to mention its name around Kara or the fact that it specifically weakens Kryptonians because that would change historical fact since teenage Kara at that point in time is not aware of those facts and doesn't become aware of them until she is shot by the DEO with Kryptonite darts. The reason I state this is because - Kryptonite (which was named that by J'onn - The Adventures of SuperGirl - Season 2, Episode 1 [23:21 - 24:20]) was something that Kara did not know the name of or that it specially weakens Kryptonians until she was in the DEO (conversation between SuperGirl and Alex - "Stronger Together", Season 1, Episode 2 [14:17-14:40]) in which Alex and Supergirl are sparring and Alex brings SuperGirl down on the first punch and Supergirl starts by saying - "How did you do that?" "Kryptonite emitters, they are only at 18%, not enough to permanently harm you but enough to weaken you and make this a fair fight," "I just found out last week that Kryptonite exist - only the DEO knows that it can hurt me."

This is the last time we get to see new episodes with Melissa and her absence in future episodes is not successfully filled by episodes based only on her team members.

Kara will be out of the Phantom Zone by the end of episode seven at the latest. After that Melissa was/is back with the rest of the cast. There's no reason to think Melissa will be absent for any part of episodes 8-20.

Total agree. It is my hopes that no episode is 100% Melissa free and we get these clever PZ inserts until episode 8. They are a most excellent story device.
