Deus Ex Machina? I don't see it anywhere, to eb honest.
Ellie was unforshadowed, came out of nowhere at the end to resolve the unfinished business of finding what happened to the old lady that the gang offered to do before she came along, saved the house from demolition, and spirited Espurr away back to Lisa (her grave that is), resolving its primary character motivation that started the whole plot of the episode in the first place.
If that isn't a Deus ex machina I don't know what is.
