*facepalm*
Have any of you actually read a FULL description of Episode 8 of Coded?
He needs to restore the memories of Xion, which in turn, saves RAX from their Torment.
Throughout Episode 8 you learn that Digital Sora is in 'Torment' over knowing that he is forgetting everyone he meets and when he states this Digital Roxas say, "You know understand true Torment"
When Xion is remember she, Roxas and Axel, are saved.
Namine is also out of her Torment. When Digital Sora said 'Thank You' to her, that released her from her torment.
TVA's needs of saving are obvious.
