The Sides of Jack We Still Need to See on 'This Is Us'

While This Is Us has alluded to hardship in Jack's life that made him into the man who ran back into his burning house -- and later died -- for the dog his daughter was distraught about, we have yet to see anything from Jack that shows him as anything other than the perfect, untouchable man we've come to know. It's time for the series to dig deeper into Jack's life, since we know how he died now, and show more sides to his character.
