sigh... these relationships between characters...
ok, let's see...
For me, Ali acted with Littlefoot like this because she met ANOTHER CHILD LONGNECK. I believe there's not any other children with the same age in Ali's herd, plus, she feared other species very much (answer on keeping him from others). So I wasn't surprised she acted like that.
Curious lovely smile? Well, the same was in Ducky&Littlefoot meeting scene... New relationship? Anyone?
Thank you, Cera, for your stubborn and bitchy character in original movie. Or people would misinterpret your greeting look towards flathead.

Now more seriously:
I wanted to post long post about why I *almost* don't want to see any romantic relationships in current canon LBT timeline and in the most of others fanstories, if some of already familiar characters are involved. But I rather would say more shortly.
Even since I got this "hate feeling" that was formed in me after observing many movies and cartoons, with endless obvious idiotic romance lines, and reading communities, who wants to see, talk, write and read about romantic relationships... Even since that, I do NOT completely reject possibilities of romance in films.
Now... Let's immediately move from general to specific: to our LBT characters:
First: Characters are kids, even during events of last movies, where that definitely grew up a little. So, it is very hardly to feel that strong feelings to other person.
Second: I believe that they, as people in our normal usual life - they won't fall in love with FIRST person they ever saw!
In case of Littlefoot and Ali:
Let's talk honestly:
In LBT4, they're just VERY young kids. Kids with their problems that united them for some time: Ali couldn't find any friend for games and talks because of racial problems in early LBT films and her raised uge fear of any possible contact with other species, kids or adults, later, Littlefoot's grandpa got ill very bad, so Littlefoot asked Ali for help.
Both they, with rest of the gang joined later, did huge adventure that solved both of their problems, and after that their herds went different paths.
They almost didn't have a lot of time together. They almost don't know each other due to this lack of time!!!
conclusion: during their FIRST meeting, there's not any chances they felt something.
Now, after their later meetings, including TV episode and some amount of time after that before Ali's departure, and all possible other meetings, till they grew up. Is there a chances they feel something, and later, step into net step of relationship?
Well... Yes. (even considering my personal experience in that)
But this chance, on Littlefoot's side, for example, is equal with any other longneck's female, since Littlefoot is very communicate character (Not as me... :'( ), and I believe, he will go into more huge adventures.

I'm writing a story that includes some sort of romance between Ali and Littlefoot
I hope you're writing about grown-up characters?

Otherwise...
YOU'RE ON MY LIST.
