How much does the MC imply he knows shes lying? He makes an offhand mention of tattoos but by the time they are at the restaurant both are more or less acting like they never vanished for a day/multiple days
Either way it is still a negative point towards player agency because in the same update we are given the choice to trust someone who lied to us....Why not give skylar the same choice?
A hacker/impossibly talented programmer claiming to be the reason someone did not show up at work/was in the hospital is not tangible proof......she is creating AI's that are hilariously ahead of what we have now she can look into someones medical records
(or pay one of her many hacker associates she met via bitcoin) we didnt see the bat, didnt see a picture of her at the scene etc
