What Was Applejack Going to Say to Trenderhoof?

I'm sure you all noticed Applejack's long pause when Trenderhoof declared that he wished to live on a farm (bless his heart...), he was sad to hear that he could not stay at Sweet Apple Acres, and asked why not. Applejack responded with "uuhh..."
This could mean anything, but this is Fimfiction.net, and basically, logic ain't gonna cut it! Logic says she would come up with an answer like "We don't have room", or "You're a stranger, why would I let you live with me?" I'm sure it's also logical she could have been a bit creeped out by the fact that this stallion who was in love with her, although she didn't like him at all, would even consider asking to live with her. But I digress, I think a good few thoughts would be, aside from logical response, "I'm in love with some pony else". Yeah I said it! I said she would say that she was in love with some pony else. It could be any number of ponies *koff koff* rainbow dash *koff koff* and it would hinder her or just seem weird. I think this would be a good fan fiction, but it would be hard to find a solid base for a story like that. Example of how I plan my stories (it's the same way I grid a sentence):
What is the conflict? Applejack is in love with Rainbow Dash, but Trenderhoof loves Applejack. What is the motive? Love. What is driving Trenderhoof to his goal (Applejack)? Love. What part does Rainbow play? I don't know! You would have to base this story on the episode itself, but it has no Rainbow Dash in it, and no way to tie these three in here without it getting weird or forced. I could have it be Rainbow is in love with Applejack and decides to pursue her, but thinks she is in love with Trenderhoof, but this was supposed to be a story about Applejack's conflict with Trend, and if I focus on her, then where is Rainbow? How do you alternate between the two to make it good for reading, because this seems like it would be best made with visual gags, therefore should be animated. No way could I put Trend in first person view, or first or even third omniscient with any character! There would be no way for it to make sense! No pony else was around for the story, and this took place within a day, so there would be no room for the rest of the gang to take notice within that short bit of time. I will think more on it, I might find a way to make this work!
