Warning: Do not read ahead if you want to avoid spoilers for "Game of Thrones," as well as speculation about upcoming plot lines.

When "Game of Thrones" premiered on HBO in 2011, the main cast of actors were still relatively unknown. Some of the show's talent — like Isaac Hempstead Wright who plays Bran Stark — were as young as 11-years-old.

With season six starting on April 24, now's as good a time as any to take a look back on what our fan favorites looked like in season one.

At the start of the series, Jon Snow was living in Winterfell as the bastard son of Eddard Stark, Lord of Winterfell, and Warden of the North.

He volunteered to "take the black" and join the Brothers of the Night's Watch after Eddard Stark was named the Hand of the King.

The last episode ended with Jon stabbed repeatedly by his Brothers of the Night's Watch, who found his dealings with the Wildlings traitorous.

While producers, actors, and even the president of HBO programming himself have insisted Jon Snow is officially dead, fans are not convinced — there have been repeated sightings of Kit Harrington, the actor who plays Jon Snow, around next season's set looking very much alive.

When we first met her, Sansa Stark was the eldest daughter of Eddard and Catelyn Stark in Winterfell. She adored love stories and longed for the excitement of the capital.

She spent all of season one trying to gain the favor of Joffrey Baratheon, her intended, as well as his mother Queen Cersei Lannister.
