@allenT 'Papa' is clear and relatable, to me it sounds like something major involving the MC's father is going to occur in that episode. Also the episode's preview image can hint at the emotional weight of the chapter without having to use words. Keep it up!
For me It's a play on the comic's name I'm ̶n̶o̶t̶ A SICK BOY
so each official chapter is "I'm A [insert word] BOY"
purposefully left the first webisode with a different naming scheme as it's just an excerpt from an episode further ahead.
Some chapter names may represent a specific character powers eg. I'm A Spit-making Boy, I'm A Wolf Boy, I'm a Liquid Boy, I'm a Gravity Boy
Videogames are a major influence, Season 1 inspired by Survival Horror while season 2 is inspired by Action, Fighting games so the genres have an effect on the tone of the titles too. eg. Season 1 includes I'm A Stranded Boy and I'm a Survival Boy, while Season 2 name example is I'm An Action Packed Boy, I'm A Deadly Boy, I'm A Tournament Boy
Some may also display emotional weight eg. I'm A Naughty boy, I'm A Forgiving Boy
I don't have a fave title as of yet as I'm still early in the series
The term 'Sick Boy' is a derogatory term used by civilians to refer to those who became carriers of a deadly virus while also displaying unusual abilities (most appear to be male, include the heroes too). I was originally going to avoid naming any of the chapter's 'I'm a sick boy' but if I do, it would probably be used for the final episode: to describe the antagonist or a sarcastic manner.
