3. Reality Itself Will Be In Danger
We knew from the previous trailer that Earth would be threatened in
Thor: The Dark World (as we saw a big black mass smashing through what appeared to be London, England). We also knew that Asgard would be under threat. It was also hinted that the universe as a whole could be in danger. However, what we've learned from the new trailer is that the entire fabric of reality itself could be vulnerable to the threat in
Thor: The Dark World. The scene in question shows Thor's love interest, Jane Foster, staring at a strange, glowing red object and is followed by the line
"the very fabric of reality can be torn apart". How Thor and his band of heroes will put an end to such an enormous threat remains to be seen, but it will surely make for one hell of an adventure.
