I wondered about #1 definitely. I also didn't understand why his friend abandoned him for some random dude so easily.
I think you are seeing it with a comic book readers eye, like I do with most these things.
As in painfully and wondering why they changed the origin of Drax or Rocket Racoon? Why Ego the Living planet had a fight within himself as a 'body' instead of just you know being the planet? Made Ultron a product of the ego of Tony Stark instead of the gilt of Hank Pym? And where the heck is Wonderman? Vision needs his mind.
Hmm, pie.
