I actually think she means to protect the next heir so the egg
Rose here indirectly means little egg. Since Child also has Langeres blood, Grandma doesn't want any tragedy to befall it. Odea Royalty might try to get rid of this kid (sinful blood, according to them).
Im so dumb but what does the rose stands for /means? Im sure, it's not just a simple rose. Does she mean to ask frera to protect his son ?
