Other non-Deus Ex Machina resolutions:
• There are no encrypted memories; Bubbles got on the table for some other reason and CW implanted fake memories of her traumatic military service in order to enslave Bubbles.
• Bubbles reminds CW that if the encryption key is destroyed, there's basically nothing standing between CW and a. Bubbles' vengeance; b. Station's vengeance; c. Faye's vengeance; and d. prosecution by Basilisk. So CW better not destroy it. Bubbles then reveals that she was trained in anti-AI torture techniques, and that she is going to start using them on CW unless the key is forthcoming. So CW doesn't dare destroy the key, and faces some very unpleasant times if she doesn't give it up.
• Bubbles and Faye go over CW's head to Big Fish, and let him know that large orbital guns are ready to take out both the skate park and lots of Big Fish's other property, and CW gets fired. On the run from Basilisk, Station and Bubbles, CW finds someone to eliminate her own memories of the key, and to transfer her to another chassis so she can't be found. That person turns out to be... Pintsize! CW ends up literally as a toaster, and Bubbles gets the key from Pintsize, who fished it out of CW's memories while she was on the table.
• Bubbles resigns herself to never getting the memories back, but also refuses to take violent action against CW. Faye and Bubbles open their own AI repair clinic, and life goes on. Then one day, after Basilisk finally shuts down the skate park, who should show up at the clinic door but... CW! CW, down on her luck and badly needing repairs after a run-in with some other pissed-off colleagues, agrees to trade the key to Bubbles for repairs. So they put CW under for repairs. At length she wakes up as... a toaster!
