Millie did not mean to behave like she was on the upper hand nor she was a person who would shift the blame to the other side. She knows whose fault it is bigger and to be frank, she was willing to accept that it was their mistake in the first place. Moreover, blaming Kara would not do any good for her, and neither for her granddaughter.
"I am sorry, I made a bad remark just now. I know you have tried your best to bring up my granddaughter into such a fine woman. Please ignore what I said earlier. It was just the spur of the moment and all those details that I came to know in one shot made my brain fuzzy." Millie said and held Kara's hands to show that she was sincere with her apology.
Kara removed her hands from Millie's grasp. She wiped her tears and looked at Dina once.
