Headscratchers / Three Guys That Paint

Spoilers will be left unmarked here.

• Why did Morwenna unlock the toilet door for Nigel if she knew it was a portal that lead to potentially dangerous aliens?
  • She probably was not aware of the toilets being the portals at that point, and just honestly didn't know.
• What happened to Alicia's parents?
  • It's left ambiguous as to what happened to Alicia's original parents, as well as whether or not Nigel ever knew them or was related to them.
• Why did the dinosaurs murder the man in the basement if they took the other humans peacefully?
  • What probably happened was that the man, in self-defence, started attacking the dinosaurs, breaking the stun gun in the struggle. The dinosaurs panicked, and killed him.
• Why was Nigel okay with taking Alicia to the basement when he knew dinosaurs would be there?
  • Word of God says that there was a deleted scene where Nigel recognizes that everywhere Morwenna goes disaster will come, and also that, ironically, the safest place for him and Alicia is by her side, because Morwenna always wins. Of course, it works.
