Yes, mother-figure doesnt mean mother

She definitely didn't treat them like they were her kids...

Its more like an orphanage than a home and I dont think she signed any papers or claimed them really. maybe adora idk

Yeeeahhhh Hordak just dumped adora for SW and porb also catra from a portal, no idea

I did not understand the question so I pressed no

I was asking, are Catra and Adora orphans? Even if they have Shadow Weaver as a "mother figure. After all we don't know who their parents are

I think yes for your question.
