I don't agree with you on that last bit. I watch a lot of stuff and keep up many things, and yet I still have time to work and handle my duties. But this was a fun video to react to.
They know all that stuff. They're having fun. Hemsworth says he's the God of Thunder so many times in those movies it'd be crazy for him not to know. And even if Brie Larson only knew what was in her movie, by that time people would have asked her about the other Captain Marvel so many times. lol
