Raha through sacrifice forced her to accept that there were things she couldn't defend against & he would step up to handle it if it meant he could keep her safe. Erenville through his recognition of her fear & his desire to ease it made her feel like he would shield her from the memories of them.

It's like...one shielded from the effects of fate. The other shielded her mind & gave her a safe space. Both helped her to grow around her helplessness & gave her strength to regain her own agency again. So Raha still looks out for her on the battlefield, Erenville w/ other Viera, she relies on them
