768 Cale, Thor

639 Garrett, Thor

Latest two are correct; list updated. Now I can mention that when I reached Cale in my list of characters to add, I did doublecheck because the image looked so similar to Garrett's that I thought I had already added him; sometimes characters on my list do turn out to be the same one under a different name, or I'll initially miss that they were minor characters who appear in multiple sources (in part 1 I had to remove a minor SHIELD agent once because he was in both Avengers and Agents of SHIELD). In this instance, the tip-off in the uncropped image is that they are holding different beverages.
