I agree. I highly doubt the studio would want to make loki that unrelatable to the audience, the one thing most ppl can relate too is a mothers love. Also when loki was given the news he trashed his room and was alone so i feel that was a true geniune moment for loki to show us his true feelings (love) for her.
