Com'on guys - don't be shy! A little bit discussion won't hurt anyone.
Or do you want me to ... get started with this?
If so - I'd say: I'd love to see Amy Brenneman guest starring. Maybe as a client of Mars Investigations or as a love interest for Keith, or as Trina's mother or as a teacher at Neptune High. I'd be okay with anything... because hell, it's Amy and Amy is adorable. Amy on Veronica Mars would be even more adorable.
