Loki always saw Odin as his father...(I'm not going by the film Thor, ok ?)...So Fenrir would sort of be Odin's grandson....and Loki doesn't reign for a while at all, not even a second...Ragnarok ends with Loki's death at the hands of Heimdall...and the Midgard serpent that you are talking about doesn't kill Odin, but Thor...Jörmungandr and Thor fight and kill each other off...
