Spinnerette

[TF-Viewer]

Now that I've had some time to think about it. I think Alexis knew who she was. She probably did need Spinneret's blood all along because of the spider DNA. Notice she didn't take blood from the other two, just Heather.

Now they'll probably all three attempt to overpower her, as the technique she used to subdue Alexis couldn't be used on three people at the same time.
