Well, I figured that since Rose's board has some red, it might as well be red rockfoil! The gang would obviously suspect that something went on during their stay, and Rose would glare at them and explain that the pin they gave her broke! Hell, even Kenna is one, that's why I love that you added the rockfoil to her board too! If Henriq asks more about what happened in Galvez, Rose would proudly mention how Kenna managed to carry half Rose's body weight on a week-long prison diet, during the time that Rose got bitten by the beast! Suffice to say, I just love how a flower becomes a symbol of strength! White rockfoil for Henriq, who never once changed who he was despite everything life threw at him, red rockfoil for Rose, who might've been hurt and damaged but never lost the will to live and fight! XD
And because Rose was under the impression that Kenna never thought of such things, she didn't suspect Kenna to pick up on anything! It's a very high-stakes moment...it would be dangerous for a glamoured Kenna to sleep with the target because one, if the glamour breaks, she's meat, and two, Kenna is demisexual, the acting would be very unconvincing. Rose, at least wouldn't need to be glamoured...she's less likely to be discovered and killed. Like, the only way that could stop Rose's hidden feelings running wild would be one of them saying "Hey, it's either you take the chance and we all come out alive and free...or we surely will all die. It's in your hands, Rose." This will momentarily allow her to recover from the mention of Henriq and agree. Then after the mission, she'll definitely ask Kenna privately about it! When Rose hears the truth...she'll then reveal to Kenna what exactly happened with Aidan...and how she thinks Henriq is too good for her, because he's just...the opposite of Aidan...honest, kind and unafraid to fight! Rough around the edges but real, rather than smooth and charming yet deceptive. XD It would be up to Kenna to reassure her. XD
