Barry had regrets. Kara had regrets. Barry wasn't fast enough. Kara wasn't strong enough. Barry watched her die. Kara watched him die. Barry is shattered. Kara is broken. Barry is alive. Kara is alive. But they're both dead. (I do not own anything if DC or TheCW. Rights to them.)
When Barry is thrown into Kara's Earth, he finds more than just a friend in her. Kara, being devastated after MonEl's passing, seems to connect with Barry in a way no one can for one reason: They've lost eveything. Or have they? ----- DISCLAIMER: I don't own this characters, they belong to the DC comics universe.
