Great episode but a little over the top with the emotions. Colby was the cool head in this episode who knew when to rest. David was showing his lack of experience during this type of event. He didn't know when to rest and as a result was acting out of sheer emotion. Colby had to save his rear which made for some nice moments between them.
Charlie was good but again, too emotional for my tastes. He really needs to man up a bit :-)
I loved the ending with Charlie, Don, and Amita sleeping in the living room looking exhausted. Very nice episode.
