okay but you know in the pilot Cecil's first reactions to Carlos seemed to imply that there was something strange about Carlos that everyone responded to ("we all hate and despair and love that perfect hair in equal measure").Â
What if when Cecil fell in love, instantly and dramatically, he just assumed there was something mysterious and strange about Carlos, and everyone was affected by him in the same way. Because, you know, night vale.
Now imagine Carlos assuming that there was something strange about Cecil, because, you know, night vale, and that's why his pulse and respiration rate increased slightly around him. Also there's this slight light-headedness? Like perhaps Cecil is somehow decreasing the oxygen concentration in the air around him? But a similar - though slightly lessened - effect is also observed when simply hearing his voice on the radio. It certainly merits further study.
Now imagine respective friends eventually sitting them down and just -Â no, sweetie, that's just what it feels like to fall in love.
