Scenario 1#: Travis has decided to host a Halloween party at the Psycia household and has personally invited you, your crush and tons of other people. The party was late at night and Travis and Crystal and Kate decided to go as their Kaliacian forms but added a bit to themselves like Travis has decorated his tail with dangling little pumpkins and he put on some fake blood on his face and hair, Crystal was wearing some fake but sharp fangs and she used her magic to make a dark aura around her and finally, Kate started wearing some dark make-up with her hair messed up and wore a black cloak.
Travis warned everyone that they better watch out for Kate who was basically lurking in the shadows and loved to scare people as her main goal was to scare everyone at the same time.

Scenario 2#: basically the same expect it was you hosting the party but you were kinda unaware of Kate's plan to scare everyone but you kept your lookout because you knew how much Kate ADORED Halloween and how scary she is on the spooky day

Scenario 3#: Make it up!
