There was literally a flashback from his past life when he said that
The 7th prince did regress because he talked about preventing MC entering Flint Howard’s territory in the same scene.
The background color outside the comic panels was white so I don’t think it was a flashback
Ikr i thought i read it wrong but no he def regress and was like even in this life, I’m gonna have her
I know he regressed. Im saying the flashback was a memory he had
I feel like the seventh print is also reborn and has the memory of previous life and that is why he’s like she was my woman and will be my woman and as for the sister Isabella I feel like she is actually alive and by some help aka her brother she left with her lover Cause like only a finger is found that’s suspicious.
