1) The dog walking issue:
It's the first and last time that we've heard of it. Plus what happened the next day and the day after that...? Did Eddie miraculously change his routine? Did they hire a dog walker? Did Frasier agree to cut short all his evenings in order to walk the damn dog?
2) Flash back Martin complains that his sons don't like him. Yay! Way to go Martin! Booting your son's wife's car will go a long way toward patching things up between the two of you!
Plus Martin is a criminal investigator, booting cars is not supposed to be part of his job, unless maybe the car is somehow impeding his investigation but even so I don't see how putting the boot on it will change anything.
What father behaves this way toward his son? Not mine and not any father I know of.( I also find it a bit grating that Martin found so funny that his son Frasier who provides him with room and board and physical therapy, sunk a small fortune into that failed restaurant venture. Way to bite the hand that feeds you!)
3) Martin says that the doctor said that he'll be out in a couple of days. What??? He's just been shot in the hip! I am no expert but I imagine that moving around so soon after a bullet ripped your tissues apart is likely to do more damage and cause internal bleeding.
