I understand. The point isn't that they are actually related, its just that a certain kind of relationship which seems antithetical to romantic love was a distinctive part of the Toa Mata. The example isn't to say that they are related, but to illustrate the point with an example of another relationship which is antithetical to romantic love.
Looks like I'll be getting the chart after all.
Roughly speaking, relationships fall into three groups. Not all relationships within the same group are necessarily the same, but they are "compatible," they can coexist between the same people, while relationships which fall into different groups are "incompatible," in order for one to exist, the other must change.
(Is it weird that I just so happened to have this lying around? )
We are saying that the distinctive team dynamic within Toa Mata falls into the "equal/alike" section (on the far right), while another like the Toa Ignika have a dynamic falling very squarely the "equal/unlike" section (middle), leaving that group far more open to romantic relationships.
We are not saying that the team dynamic can't change, but that for many of us, it is a "core" part of the Toa Mata team (personally, it's the only part of the team I actually care about), and we just want to make that clear to others going forwards.
I'm thinking maybe we should just leave this discussion here and debate the merits/faults of individual ships.
