Let me see,” Reed said, grabbing another device and running it along the length of Rocket’s spine. “Hmmm... that’s curious... According to my scans, there are traces of all sorts of alien DNA in the codex. That’s to be expected, I suppose. But there’s also something that is a near-perfect match for a species found here on Earth.” ”Really?” Rocket inquired. “Back on Halfworld, they experimented on all sorts of animals. I may be the very best of the lot, but it’s possible someone else got off that miserable planet and made their way to Klyntar. The question is, who?” ”All I can say for sure is that they had the characteristics surprisingly similar to the genetic subfamily Lutrinae,” Reed replied. "That don’t ring any bells,” Rocket said, scratching his furry head. ”Here on Earth, we more commonly call them otters,” Reed added. Rocket’s eyes went wide. There was only one otter he knew back on Halfworld, and she knew him more intimately than anyone else in the galaxy, including Groot. ”Lylla...” Rocket whispered under his breath in astonishment.

LIKE I KNOW THIS STILL A BIG IF BUT LYLLA MAY STILL BE ALIVE! AND SHE BONDED WITH THE SAME SYMBIOTE ROCKET DID IN SEASON 3!

Its implied it chose rocket because he was someone important to its previous host.

this seems like 50/50 chance of being a wild goose chase, in comics a codex has been used to track some one before but it's not definitely proof there alive.

Both ending are so intriguing for rocket as a character, yeah a little part of him died when Lylla died and he's poked and prodded that wound ever since

Buts hes moved on now, this might change things though
