Please excuse spoilers. This is my first time here and this is playing on my mind.
OK so I just watched Thor 2, which was pretty damn awesome, but then at the end Thor and Odin have a nice little father-son chat where Odin recounts to Thor saying "You once said to me you would never know a wiser king than me."
All sounds well and good yeah, but then
Odin actually turns out to be Loki who has duped everyone into thinking he is, in fact, Odin and is now the king of Asgard.
"So what's the problem?" I hear you ask. Well, That point where Thor said "I will never know a wiser king than you" to daddy was at the end of the first Thor movie, after Loki had fallen from the bifrost over the magical waterfall into space/the universe/a magical little vortex thing and disappeared forever... until he came back in The Avengers.
My point is, how could Loki have known what Thor had said to Odin? He was in some strange temporal plane thing neither here nor there and definitely not in Asgard eavesdropping in on his adoptive family...
