in short, suspect people for good reasons. like ive only ever seen early game scum skitter but i mostly remember her saying lots of reasonable things that most people would agree with and couldn't really be disputed that easily.
so id think she would express some paranoia around you and/or datisi to keep those options open but i don't really think she'd jump to you as a team right off the bat and then also back off right after. as someone widely townread she doesn't really have to lead and can just prod around a bit and let other people convince her of things
her reaction does follow from what she wanted earlier, so it isn't like out of nowhere, but it feels like she just jumped headfirst into the fire for no good reason... ok actually wait there is one possible good reason which is if she is partnered with irrel/mena. but anyway outside of that i just don't expect scum skitter to do things for no good reason
maybe im wrong on that and if you can convince me that there is a good reason (outside of just matching town tone, don't think she needs that) or of her doing similar things in the past as scum then i can reconsider
