A ship between the two characters Sara Lance and Ava Sharpe from the show Dc's Legends Of Tomorrow. They had their first date in 3x12. They got engaged on episode 6x07 and they got married in episode 6x15.
Avalance is one of my favorite ships.
Frostllegra is a ship between the characters Allegra Garcia and Frost (Frost's name was Killer Frost before) in the show The Flash. They are not actually together in the show but a good bit of people ship the two of them together.
