Seriously, who eats pizza at a movie theater?
I think so, yeah.That raises a question: Was the intermission in #301 a flashback to the sentient movie-theater snacks world? I think #1140 implies it was, since the context of #1140 #1140 implies it's a flashback to that world, and in that strip Soda is getting revenge on Pizza for killing Milk Dudes in #301.
People can and often do have multiple layers of motivation, yes. Redcloak might prioritize one house if pushed, but if not pushed he does live in both, for example.
