Rebecca maintained her typical look from before even when Serenity got right up in her face, Rebecca's eyes slightly narrowing as Serenity did so. The way Serenity smirks at her, is she trying to be intimidating towards her? If so, then it didn't work. Although, Rebecca got a sense of satisfaction from Serenity, as if she was interested in her in some kind of fashion. Yet again, it seemed like Serenity took interest to other members as well, such as Vivian for example. Just then Rebecca watched Serenity responded to the tank again, Rebecca was half listening to what they were saying. Something about backstabbing or some other. Rebecca almost reacted to the drawing of Serenity's rapier, but before she could Vivian stepped in and therefore remained silent to see where it would go. If the predicament were to go any further, Rebecca would be prepared on how to interfere.
