In-Betweens
The cleaned dougas are then sent to the in-betweeners to animate the weird in between pieces that are between key cels/sketches. Some are great looking others can just be awkward because they were never meant to be seen! The way to identify an in-between is the number will be something like A2 with no circle, triangle, box, or dash around the number. A notation around the number would mean it is a key cel.
