Why did you marked Series:Portal as a child of Series:Half-Life?
Topic on User talk:SirYodaJedi
I did so because it seemed logical at the time. It isn't exactly a proper spinoff, but it takes place in the same universe and has sometimes been marketed as a spinoff.
After you asked this question, I asked for thoughts on the discord. They said we can go ahead and keep it that way, since they are both short series to begin with.
