Worth sharing the key art they released at D23--
The way Red Guardian and Melina are on the right and Yelena and who are presumably the other trainees of the Red Room are on the left seems like a pretty intentional subdivision, with Taskmaster separate from everyone else. My guess is that Melina recruits Yelena and Black Widow to help them free Red Guardian and the other trainees but it's revealed that Melina and the Red Guardian are actually trying to kill the trainees or sell them out or something, and that Taskmaster is someone who is working for a third party that has none of their interests in mind. Just my shot in the dark, the teaser doesn't tell much of anything in terms of actual plot details.
