I think that JB originally thought the case a quick cake walk towards fame and fortune ... but then they discovered Caylee's remains and it became a DP case. Rut-roh!
JB obviously had a short-term game plan that was based on the ~$200K but this spun out of control and now ICA is theoretically indigent and JB is locked into a long drawn out and involved case.
Maybe ICA is going to do the Depos so JB can focus on other work that will make him money. ICA will earn her keep.
