A series of official character descriptions for Thor 2 have landed online where we get an update on Tom Hiddleston and Loki as well as Rene Russo and Frigga.
Slight spoilers follow.
StitchKingdom was provided the following Loki description revealing Frigga (Rene Russo) still remains close with her son.
Loki Laufeyson is the adopted brother of Thor, raised alongside him from birth by Odin. Upon learning his true lineage, Loki sought to conquer both Asgard and Earth but was stopped by Thor and the Avengers. Still arrogant and unrepentant, Loki sits in the dungeons of Asgard, with only his mother Frigga seeing any hope for him. But when an ancient enemy seeks the destruction of Asgard, Loki finds his loyalties tested.
And the description for Frigga:
Frigga is wife of Odin and mother of Thor and Loki. The glue that holds the royal family together, Frigga knew that there was more to Odin’s banishment of Thor than met the eye, just as she now sees that there’s more within the villainous Loki than the others see. But when Asgard is attacked, Frigga will fight to defend those that she loves at any cost.
Following the pic is a potential bigger spoiler.
It's speculated that Frigga dies in Thor 2, which the description seems to hint at.
