Irene was just around the corner from Felix when she heard his utterance of: "My heart was yours already. Now the mountain is yours. My life is yours. I will kill every one of those monsters, knowing what they took from me."
It struck her enough that she had to stop for a few moments and breathe in and out calmly as she tried to control the lump that was forming in her throat.
In the life she saw, she didn't know a love like that. The man she was married to was an arrangement of convenience. She was fortunate that he at least respected her for who she was and didn't force her too far out of her comfort zone.
For some reason, seeing Felix crumble because he lost his love was making her equally long for as much as resist a love so incredibly pure. Few must have been lucky enough to experience that feeling. The thought made her heart race.
