You were pretty new on Knowhere. The guardians brought you with them after they found you on one of their missions.

As you were sitting at a bar, minding your own business as you feel something nudging your leg. When you look down you see a golden retriever–labrador mix sitting in front of you, looking like she's frowning.

Cosmo: "You! You won't believe this! He called e a bad dog!" She seems to use telepathy to talk while pointing to a man with her snout, who just rolls his eyes at her before responding. Kraglin: "And I won't take it back."

The dog growls before suddenly an empty soda can flies towards the man, who just dodges it before coming over. Kraglin: "Don't mind her. She's always acting like a bad dog. My name is Kraglin. And that is Cosmo."
