Yes
However the problem here is she isn't so much older as was frozen in time. She may have reached a higher stage in advancement of power but she is acting all high and mighty like she owns the place but is being restrained. She is being restrained but doesn't own anything. I believe it's more she doesn't accept the MC since she listens quite nicely to the other witches when he isn't there despite her stubbornness in mindset (which doesn't seem as much as before)
yes yes, i agree with you
think of her as an alien that came from a whole different universe. She just needs to see with her own eyes XD
im annoyed at her so much but can't hate her since she is a grandma (mindset) u know, some elders have close minded cuz they have strong/firm beliefs from their ancestors, etc.
