Ok so before I got to play this game, I actually thought Bela was a girl. Reasons:
1- I don't know he kinda looks girly.
2- Bela is a girly name.
3- So what do we know about bees and wasps, Queen bees are female but Bela is under control of the queen not is the queen. He/She can't be a worker cause they are only used for reproductive work and THAT IS DEFINTALY NOT BELA'S JOB. So He/She can only be a worker bee.
The thing is. Worker Bees are only female. So Bela can only be a female right? So yeah and then I watched EpyksLion's playthrough and yeah. Bela is a boy.
