I think K-9 might be Meg the demon because Shy said 'Since when do you want to help anyone?' And hunters would be naturally wary of a demon, and her response was 'Oh Shy I'm insulted right now.' Now either she is being sarcastic and doesn't care somebody judging her for some reason or she is generally insulted that somebody is judging her. Now if she is Meg it would make sense she is being sarcastic and doesn't care if a hunter is judging her because she is a demon, as she would be used to it and if she is being genuine it could also make sense considering Meg goes out her way to help people since she joined the hunters and might not like the fact of being racist and judging based on the fact she is a demon. Obviously it's just started but it's an idea.
Same with Crowley, if he's a secret role.
