[EX Q]: CONTEXT: I would suggest that the Teletubbies are not cyborgs. The peculiar antenna and visual display appendages are naturally occurring adaptations which allow them to exist in symbiotic harmony with humans. They display a distinct and uncontrollable physiological requirement for the reception of (mostly) childrens basic and crucially, innocent thought patterns. This coupled with our own natural requirement for congnative and social development; the 'Tubbies' use their individual personalities and applicable talents to display moral and ethical guidance, through the performance of simplistic song, dance and play scenarios... I would therefore classify them as Symbiote.  <sep>  Q: Are the teletubbies cyborgs? A: I would suggest that the Teletubbies are not cyborgs  Q: Why would you come to this conclusion when they have implanted televisions? A: The peculiar antenna and visual display appendages are naturally occurring adaptations which allow them to exist in symbiotic harmony with humans 
[EX A]: Are they the result of some kind of experiment?

[EX Q]: CONTEXT: By the time of Infinity War, they could not have kept the Infinity Stones in Odin's Vault, because of the events in Ragnarok, which, by the end of the movie, left Odin dead and Asgard destroyed. The Asgardians wouldn't have kept the Infinity Stones in the Vault before Ragnarok either, because they knew that a cataclysmic event was coming, even if they didn't know when, so it would logically be safer to keep the stones away from Asgard. Finally, just as logical assumption, if you have a super-destructive device in six parts, it would make more sense to keep those parts as far away from each other as possible so that it would be more difficult for said weapon to fall in to the wrong hands. If they're all in one place, no matter how secure, that only makes it easier to collect all the parts. This is doubly true since Thanos is literally one of the strongest characters in the MCU at this point. Anyone who would have been powerful enough to stop him either (a) wouldn't care, or (b) have already been killed.  <sep>  Q: Why didn't the Asgardians aquire the Infinity stones using Heimdall? A: because they knew that a cataclysmic event was coming, even if they didn't know when, so it would logically be safer to keep the stones away from Asgard 
[EX A]: What was the cataclysmic event?

[EX Q]: CONTEXT: As at the end of Revenge of the Sith, Yoda is the one who teaches to Obi-Wan how to come back as a "Force ghost" (himself learning it from Qui-Gon), so it is possible that he comes back this way /!\ Warning, Spoiler about The Force Awakens /!\ Yoda isn't in the movie  <sep>  Q: Did Yoda appear in Star Wars The Force awakens? A: it is possible that he comes back this way  Q: Is he one of the main characters? A: is 
[EX A]:
What happens to him in The Force Awakens?
