So this is a question I think about and tonight an episode aired and im likely practically for sure its my favorite scene of any trek. Granted most of my favorite trek scenes involve spock.
EDITED - so glad I made this post. Its cool to see or hear about peoples scenes.
Lately it’s been the opening from Star Trek V. Sybok telepathically forces that one guy to relive his deepest, darkest pain in order to overcome it. It’s something I thought a lot about lately in regards to my own pain and personal trauma. If only it was that easy.
