Why Did Mason Decide To Remove Celeste’s Memories?

Citadel Episode 4

Before she collaborated with Nadia Sinh and ended up saving her life, Celeste Graham worked her way up through the ranks of the Citadel as a low-level agent.

Because Nadia thought she was worthy, she moved her up to the Tier 1 level. This implies that Celeste could be trusted with missions that were more important and perilous.

She has been given the mission of obtaining the Oz Key from the Silje brothers. She pretends to be someone else in order to seduce Anders and win his heart over to her side. 

After months of information gathering, Celeste successfully steals the Oz Key, but Danik catches her. He comes close to killing her, but the Citadel squad quickly storms the scene.

When Celeste asserts her innocence, Mason and Nadia start to argue. The Oz Key was stolen by Celeste and was found in her backpack by the Citadel crew.

The team chief received a text message from a Tier 1 officer asking them to steal the Key and bring it to the officer secretly. 

Being the sole person with access to everyone’s chats and calls, Carter found out about it. Mason came to the conclusion that Nadia was the one who wrote the message.

Mason didn’t pursue Celeste because he thought she was guilty when he did. He did it because he wanted to blame Celeste and was concerned that if she wasn’t killed, she might say or do something that would reveal what Nadia had done to others.

Well, everything he did was with the intention of saving Nadia.
