Altria is pretty... close would be a strong word since they have a contentious relationship, but she's well-acquainted with someone in a situation very similar to Ivy's but the exact opposite attitude about the whole thing, which could make for some interesting CR if Altria assumes that Ivy is secretly doom and gloom like Lara and she's just hiding it. Also Altria runs on as little sleep as possible and she can probably keep her company through the night.
