Rose pressed her lips together to keep from commenting on Dove's 'joke', sure that if she did she'd say the same of herself and the other girl wouldn't let her take any of the poisons at all. She focused on what her hands were doing, finding a funnel and a bottle to pour the two liquids into. Her hands didn't shake despite what she was doing, letting the liquid pour out in controlled amounts into the dark glass. She poured in the right amount of the first one when Dove spoke up.
She set the bottle down and corked it again. "It was good to have your company again, if only for a short while. Skaia protect you." Rose replied, smiling at the other girl's back for a moment before turning back to her work so the other girl wouldn't notice just how fake it was. She kept her eyes on the bottles in her hand and grit her teeth shut so she wouldn't call out and beg Dove to stay with her, not say that she didn't want to tolerate it alone anymore.
When she was certain the other girl was gone, Rose set down the second poison bottle and put it away with the other, going back to the table and cleaning her instruments and putting the second bottle of poison into the pocket of her dress. She grabbed a random, common, useless herb from the shelf and left the room, pausing at the door to look back into it as if her friend was still in there, saying something before leaving the room and hurrying back to the palace, making it back in time to hear that the Condesce had summoned her again. As she followed the seadweller that found her heading back to her room she mumbled the same words she'd said before leaving the room.
"Goodbye, Dove."
