Amy joined the cast for the third episode of the season. She was hilarious as an inappropriate train station clerk, who made things awkward for Claire and Sister Michael.
The sketch artist and Irish Twitter icon Michael Fry got into a row with the Derry Girls on the train to Portrush.

The Fair City actress stepped into the part of an old friend of Mary and Sarah, who they can't quite remember.
The Game of Thrones actor was the psychic Carlos Santini. While the family felt ripped off by their reading, he did prove useful in locating Grandad Joe's missing electric razor!

A special guest joined the episode five flashback, show creator Lisa McGee's husband Tobias Beer. He played the silent surgeon and dad of Jenny Joyce.

Emmet joined in episode five, and challenged James to a fight outside for Fat Boy Slim tickets. Not exactly Kin or Peaky Blinders, but he was definitely intimidating.
The Scottish DJ and boyfriend of Saoirse Monica Jackson was the one to throw the gang out of the Fat Boy Slim concert 'for fighting.'

National treasure Sinead Burke showed up in episode six as the TV host who took pity on Michelle.
Well, that seemed to work. #DerryGirl https://t.co/FhfHWElAns
