Brother, whatever you're holding onto, remember who Mother was. Wise and forgiving.

[ Thor does know that Loki said something to her he deeply regrets, having brought it up in a past conversation. He doesn't know anything else about what happened. But he doesn't really care what was said when it comes to this since he knows with certainty Frigga likely already forgave Loki the moment he said it. ]

A kind man sounds exactly like who she would want for you.
