I do like Niska's dry wit, still can't figure out if she's doing it on purpose or not. She has to be though, doesn't she?
Niska, Mia and Max are definitely three of the best characters. 
EDIT: Sorry if that all seems kinda random or something. My train of thought must have de-railed or something.

With Hester on a warpath against humans she'll take a few people with her before she goes down. If Hester can't get Mattie to upload the code to wake the synths up, maybe Hester upload her mind to all the synths as her last deed before she gets killed off. It wouldn't surprise me if they keep Hester alive have her be the main villain for series 3 to lead her brothers and sisters against the humans for the next series.
Hester only meet Mattie not seen the rest of Hawkins since Niska tracked down the Hawkins, Hester find a way to track Mattie down, since Mattie knows Leo, Mia and Max I can see Hester kidnapping one of them to make Mattie to come to their rescue, have Mattie go with Hester somewhere so Mattie uploads the code to all the synths.
Niksa changed abit while playing with Sophie, I can see Sophie being tricked by Hester into going with her since she likes synths, this will make Mattie come to her sister's rescue. It be shocking if Hester started to show some kindness to Sophie while Hester spends time with Sophie getting to know the little girl.
It would be better if Niska comes to Sophie's rescue, kills Hester, takes Sophie home, the Hawkins thank Niska tearfully and puts tears of joy on Niska that the Hawkins are not scared of her anymore.
I hope that awful human how sold Mia out doesn't stay on her mind and she rebonds with her friends the Hawkins.
A shocking twist it would be if something happened Laura or the husband and Mia comes back offers to help take care of the family.
