He was someone who had gained his memories after all, though he lied to her that it was just partial.

If her son, Blackey, didn't tell her what he saw that day, she wouldn't even believe it as well. However, there was a saying which said, 'Use people that you trust.' Since she had chosen him as a husband, Calista decided to trust him all the way.
She didn't know what he wanted from her, but what she knew was that he didn't have any ill intent towards her. Which was why her trust in him was high, even when she let him go.
It was also another way of doing the last trust test on him. To see whether he would return to her after he left for a legitimate reason.
