Does carol know about Rick in Dixon

I’m really trying to understand if carol knows Rick is alive in Dixon or if Dixon takes place as Rick is at the crm. We know Rick and carol reunite but is that before she leaves to find Daryl or after they return and Daryl just isn’t there when Rick arrives?

My theory is carol knows but after finding Daryl she realizes he has a mission in Europe and she can’t tell him. She knows him too well and if she tells him he will drop everything and become reckless to return to Rick. And potentially get himself or others killed so she intentionally doesn’t tell him.

It 100% fits her character. She doesn’t always take the “moral” path. But tends to take the necessary path.

Like the prison flue outbreak with Karen and David, Lizzie after Mika, releasing Negan to get to alpha… the list goes on. I could absolutely see her character keeping Rick’s return from Daryl for his own good. Then when (not if) Daryl learns of Rick’s return it creates tension and drama between carol and Daryl. I think this works much better than a simple (boring) Rick is in the crm at the same time as carol and Daryl are in Europe.
