Carmen Berzatto hated that Jenna Jerimovich started calling him Carebear at the age of seven. In retaliation he called her butterfingers as she was the most clumsy annoying younger kid he was ever around.
Jenna was four years younger than Carmy but practically was around his family all the time because of Richie, her uncle. Everyone knew Jenna had a crush on him everyone but Carmen. Now with Mikey's death Carmen is back and can't seem to shake the annoying girl turned women away.
