In a brief scene in "Thor," Donald Blake is the name of one of Jane's (Natalie Portman) ex-boyfriends. When giving Thor some clothes to wear, he finds a name tag of a doctor Jane used to date — Donald Blake M.D. But in the comics, the plight of Blake is far more harrowing. After discovering that he was only created to teach Thor a lesson, he seeks revenge on the family of Odin. He commences on a quest for blood, only to be stopped by one person — Loki.
Sound familiar? Both Blake and Mobius struggle with a similar crisis of consciousness. Though Mobius insists that his life is with the TVA, he has already shown signs of cracking. Mobius could very well take a dark turn in the future after failing to cope with losing his former life. Could he also snap and go on some bloody rampage? If so, this would have consequences for the Asgardians. Mobius is perhaps the only person that Loki calls a true friend, and his trust and companionship would be a devastating loss. This plot twist would also have ramifications for Thor (Chris Hemsworth), who has been featured in Season 2 to an extent. His image is depicted in the form of a wood carving when Loki and Mobius go to the World's Fair in Chicago.
Could this be foreshadowing Mobius' dark designs on the Norse deities? Only time will tell.
