Wait alice got her new phone from watcher world.
i like that in the Q&A after they talked about how the images of deb cheating on alice might have been a manipulation. either way that phone came straight from the watcher (i mean dont they all). i like to think that even tho they made it out alive, that phone is still there as a gateway/tool for blinky
I hc that solomon and steph are bill and alice respectively. If at the end of watcher world bill made a bargain w the LIB to give up his empathy for another shot at raising his daughter. There is no proof in canon except in my head.
just interesting that that not only are mariah's teen characters both heavily obsessed with their phones. (i get the joke, teens amirite). but they also hold such power over their narratives. if alice didnt have her phone, theres a chance she would have been able to convince her dad to leave watcher world at the first sign of trouble/they might not have fought. if steph HAD her phone then she wouldnt have called pete and set the events of npmd in motion. AND solomon would have intervened at the waylon house.
