I know that Dora and Flora are two very different girls, if you consider their ages, their interests, the way they think, dress, act, etc. That might explain why you hardly see them drawn together, therefore I just felt like pairing them again.
But that doesn't mean they won't have a great time when they're together. Remember that even though each of the Friendsies has their preferred friends (like any of us!), they're usually very flexible when it comes to get along with anyone from the group.
What do you think these two might be talking about?
