I'm pretty sure Casey is shitting himself trying to keep them out of deposition because there is no way in hell they go into deposition without either getting caught flat out committing perjury, or having to admit they were lying in public.
Here is what happens in deposition. They will have had a team go through all their public statements and they will have them numbered and prepared in advance, ready to be submitted as evidence. They'll also have their list of questions put together.
Everyone does it differently, but any solid legal team is going to have that stack of evidence and that stack of questions, and the questions will have a matrix associating them with the relevant exhibits, and what kinds of answers they'll expect, so they will get them and whenever something comes up that surprises them by contradicting something they said in public, or not matching up with something they already have (but have not necessarily put out in public yet), they'll have an exhibit for it.
And then they'll ask them to reconsider their answer in light of it being a complete lie. This will happen all day long, and maybe for a series of days until it is done. By default you only get six hours, but you can move to extend that for cause or because they deliberately wasted your time with shenanigans, which is also very likely.
RIP the Bearded Fellow or Amazon who ended up with this sad task...
