I left last Monday night’s Avengers screening as the closing credits began, so I didn’t see any tacked-on sequences. Movieline‘s Jen Yamato has written that there may be two, one having something to do with the plot. But the other tail-end sequence (if there are in fact two) is totally unrelated to any plot element so it’s not spoiler material. Not in my book at least. A photo is sitting on a Tumblr page. If you’re a spoiler whiner, don’t click. Simple as that.
