Baldur was much beloved of the gods. His mother (Frigga) went to all things to get them to agree not to hurt Baldur, except she forgot Mistletoe. Baldur was demonstrating his invulnerability having other gods throw things at him. Loki tricked one of the other gods to hurl mistletoe at him killing him.
If I recall correctly, Loke was bound to a stone and had a serpent dripping venom into his eyes as punishment. I would have no idea why Thor would become convinced now that the gods of the River Kingdom would have anything to do with it, or why now.
