Voice One: "You stole it! I..."
Voice Two: "I thought you put it there!"
Voice One: "Why would I put it there?!?"
Voice Two: "Kindness?"
Voice One: "Kindness?! You stole it! He stole it!!"
My initial idea was to have two squirrels arguing over a nut, pretty basic, but also pretty obvious so I'm glad I didn't use that idea (also I'd've had to try and animate squirrels, despite watching lots of Disney films throughout my youth, I doubt I'd probably fail epically). This idea arrived almost instantaneously after listening to the voice clip, (a transcript can be found above), which was a minor miracle as this was early Monday morning.
My second idea appeared not long after while we were in the 2D session breaking down the soundclip to begin the start of our dopesheets: An Angel and a Devil (like the two little guys who you always see in films acting as the characters conscience) arguing over a stolen "feeling", the ending, where the Devil would shout "He stole it!" would've panned out to reveal the character who was having a battle with their conscience, and the Angel and Devil had been sat/floating by their shoulders.
After speaking with Derek he raised some problems with my idea (he's good at doing that), in that it wasn't obvious what my characters were arguing over, whereas with the squirrel idea it was too obvious, this wan't obvious at all. He also suggested changing the Devil to the one who says "kindness?" to make it more ironic and add a bit of comedy to it. So, my revised idea is still having an Angel and a Devil arguing, but this time, the Angel is the angry one, because the Devil has stolen his Halo and got it stuck over his horns.
Now having finished the storyboard, I have recorded some reference material (with horrendous acting once again) in order to make a quick animatic this week. I still need to use After Effects to composite the two clips (since I couldn't act for the Angel & Devil at once), but I have the cut that I want to use to emphasise the "kindness" line. Also note my amazing props. Yeeeah.
Aaaand finally (this has been a mammoth update) this is a quick drawing I did in Photoshop to give a (very) rough idea of what the final thing will kind of look like:
