The Elder Ennises....
Are they Connie's natural parents, or her in-laws? When Carl enters, he refers to them as "Mr. Ennis and Mrs. Ennis".
Since Connie's nickname for Timmy is also "Mr. Ennis", and since Steve notes that as a way to keep Guy alive (by still having a Mr. Ennis in her life), I'm guessing they are her in-laws. Would that be correct?
