Bump on the Head

Mitchel bumps his daughter’s head on the doorframe, and he and Cam worry that something may be wrong with their daughter. They consider causal outcomes, like if he had hit her head she would cry (which she does), but then they worry about long term impacts of hitting her head. The two decide to call Claire for guidance.

Claire reassures them that everything is fine because her youngest son (Luke) was hit on the head a lot and he’s fine. Unfortunately, this correlation ends up worrying Mitchell more. While it may not necessarily be causal, the two worry that is and decide to take Lily to the hospital.

The Virus

Cam and Mitch went on vacation to celebrate their Honeymoon and brought back “gifts” to the family. Mitchell claims to have gotten sick because he wore socks on the beach, but his virus spread to the entire family. Each member goes through the pain they endured because Mitch didn’t quarantine himself. Only later in the episode do they find out that Mitch wasn’t even patient zero.
