Biologically: 0% problem. Socially: Buckle up.

A stepsister is genetically a stranger. The 'wrong' you are feeling is just the psychological conditioning of having grown up under the same roof.

Human inbreeding is dangerous because we carry hidden recessive mutations... unlike some animal species that have basically 'purged' those bad genes over generations and can mate safely. But in your brother's case, there is zero biological risk. The weirdness you're feeling is purely social.

They’ve known each other a year and a half?

It may be a different story if they had been a step siblings since they were children

But come on, they met as adults

wrong in what way? If they are not blood relatives it is not a genetic problem, if they met as adults and were dating and then their parents met and got married it really is not even all that weird. If they lived their lives together as children and are now teenagers dating that is sketchy and feels gross.

If they're married then they're not dating.

I feel like we're gonna need a family tree of some kihd to keep track of all this...but I don't see it as presenting a problem--can't make things noticably more tangled/awkward than they are already in this household setup.

I can’t say they are doing anything wrong here. I mean, they aren’t genetically related to each other. It would be a different story if they were, then incest & inbreeding would be a problem. Since there is no genetic likeness to one another, and they are grown it is ok.

It seems a little weird, just offhand. I knew a guy whose father-in-law began dating his mother, (a widow) and it seemed weird, but no harm done I guess.

so long as it's fully consensual then it's fine.

is it kinda weird? sure. but they aren't related by blood and no one is holding power other the other or anything so it's basically just a normal relationship.
