of-suns-and-guns:

While re-watching 1×13, it hit me that Alex has seen Krypton.

Mental construct or not, it was the exact Krypton Kara experienced as a child, and the one she remembers/misses now.

Can you imagine how many times Kara and Alex have probably fantasied about that very thing over the years?

And now Alex has experienced those exact memories Kara was recalling while telling her all those stories; she’s seen Rao, Kara’s childhood home, Zor-El, the city, the architecture.

Alex is the only person left in Kara’s life who’s seen Krypton.
