* CrowningMomentOfHeartwarming: "Colin is a blessing."
** Also his baptism in episode 2 of series 2.
** After being headbutted by Colin, harassed by his father-in-law, just missing out on [[spoiler: Joan's death]] and being heckled at Mass, Adam finding out that [[spoiler: Alex is pregnant]], and the subsequent reunion of the characters for Christmas dinner.
** The dragonfly story that Adam tells the children after [[spoiler:their beloved teacher dies]] is lovely as well as moving.
* TearJerker: Adam's breakdown at Midnight Mass in the Christmas episode is both utterly pathetic and utterly heartbreaking.
