Who Are Ser Erryk and Ser Arryk in House of the Dragon?
Ser Erryk and Arryk Cargyll (played by 34-year-old twin actors Elliott and Luke Tittensor) are twin brothers forced to serve and reside in opposing factions.
Both earning the title of being renowned knights, Ser Erryk is a member of the Queensguard under Queen Rhaenyra Targaryen in the Black faction, while Ser Arryk is a Kingsguard of King Aegon II Targaryen in the Green faction.
The twins may have gone through so much growing up together, but the separation of their duties and responsibilities led them astray from protecting each other.
In this case, this led to their final battle in House of the Dragon season 2 episode 2 titled Rhaenyra the Cruel.

King Aegon wanted revenge. Convinced that Queen Rhaenyra was behind the death of his son and heir, he ordered Criston Cole to murder the opposing Queen. Little did they know, it had been Daemon who organized the killing.
Cole had chosen Erryk to swoop into the Blacks' castle and carry on the deed while being in the guise of his twin brother. Reluctantly, he did, to defend his honor and duty as a Kingsguard.
Once Erryk drew the sword against the Queen, Arryk arrived just in time to defend her. While Erryk keeps attacking his twin, Arryk leans more on protecting his Queen, showing where they stand in this fight.
Unfortunately, Arryk gets killed when Erryk pushes the sword through his own brother. The tragedy doesn't end there, however.
Kin slaying is a terrible deed in Westeros, far too horrifying to send the gods cursing after you. Erryk knew it was too late for him. He tells Queen Rhaenyra "Forgive me" as he committed suicide out of shame for murdering his own kin.
"When he says 'Forgive me', he's saying it to Rhaenyra because he's about to sacrifice himself in front of her," Elliot explained, "But it's also directed towards his brother."
