very well written and performed scene taken outside of Star trek continuity. Why do we have to tie all the old characters together back at the Academy? Hell, in The Menagerie Kirk states that he first met Captain Pike when he took over the Enterprise from him; yet now, in Origins ; Pike is cadet Kirk's commanding officer at Starfleet Academy.
When I heard of the project, I thought they might get a bit more creative and work in Kirk's past as stated in the show itself like the incident refered to in Obsession and see Captain Garrovick (who both McCoy and the Kirk character himself stated was more of a role model).
Still, what's there does look like an interesting setup, even if it re-writes a lot of early Kirk 'history' from the actual show.
