So I’m kind of drawing a blank there on what would finally make daughter and father discuss the topic. Some event involving mothers?
Honestly as much as I would like to see this scene play out, I also kind of think that the boat has already sailed on that one. If anything, Mr. Threehorn would have to bring the topic of Cera's mom to her in a conversation sometimes soon after they got reunited in the Great Valley. Right now it would be a lot more difficult to think of a decent setting where such conversation wouldn't seem out of place... Then again, Littlefoot did sing about his mother in LBTV and it went surprisingly well.
Oh, and another situation that I'm dying to see in a LBT movie is Chomper learning about Littlefoot's mom's fate. I mean, does the little sharptooth even know what happened to her? How do you think Chomper would react if he heard about it from someone else (probably from Cera, who'd bring it up to hurt his feelings... Maybe during some stressful situation when the gang were in danger and she herself lost her cool)? :huh:
