I vaguely recall some dialogue in the script for the Rastedel part that had situational content in case Helayna had recovered (I think she was able to carry herself as a knight again and was Rowan's bodyguard or something like that). Haven't played the game in forever so not sure if her recovery arc has had any progress for act 1.
Currently in my "good guy" run I preferred to help her escape, felt like she was kind of already recovering and with enough support she'd be able to survive and maybe even thrive on her own. It does however feel like that if you help her escape she will probably be written off the game, otherwise I feel that an escaped Helayna and a "stayed but recovered" Helayna would overlap thematically, since if the later was able to recover completely then the only reason to choose to help her escape instead of keeping her would be out of loyalty to Alexia rather than for Helayna's own well being.
