If you ask me, the thing with Flash wasn't mainly because of stupid teenage hormones. After all, the blushy-stammery thing didn't even begin when they first met. It was after that. Before that, Twilight didn't seem attracted as such. That really only began after she spilled her drink on him and he didn't mind.



Which plays into what she might see in him. Mind, these are only ideas. The situation Twilight was in during that time was confusing, frustrating, and it left her extremely unsure. Left without her pony friends, without her magic, in a totally different world... I think Twilight was grateful for every bit of stability she could get. And Flash had been kind to her from the beginning. She might've latched onto that and things grew from there.



It would be a similar situation with the human Twilight and Timber. SciTwi was in a bad place, and along comes this guy who goofs around and helps her get her mind off of all the horrible worries she's carrying around all the time.
