Remira didn't know what to do with the information at hand. From the looks of it, Jester wouldn't have given her such an opportunity if he didn't know that in the end, he would somehow come out on top, so this was definitely a trap of some kind.
A trap where she might lose her life if she didn't tread carefully. But at the end of the day, her obsession won her over, since hearing what Sheva had to say, she had already made up her mind.
Even if it was a trap, she would go in. Considering that, unlike at all other times, the place where Malidi is hiding is far from the civilian population, the collateral damage caused by her actions should be minuscule.
