From the BB wikia:
Hank Schrader and Steven Gomez meet after the failed sting and discuss
options. Hank says that Jesse has a plan to get Walter, but Gomez
doubts Jesse is able to come up with something useful. They approach
him in the car, Jesse tells them that they need solid evidence of
Walt's criminal activities, but Walt got rid of any possible evidence
linked to him, except for one thing: his money. If they can find the
money, there is nowhere for Walt to run. Gomez asks if Jesse knows
where the money may be, Jesse answers that he doesn't -- but there is
someone who may know. At the Schrader home, Gomez brings a piece of
some or other animal brain and some information: Huell Babineaux has
been taken into witness protection to be interrogated about the money.
Gomez is worried that maybe the guy will call for a lawyer, but Hank
believes that he won't, under the circumstances. Hank throws the brain
on the ground and says that it's Jesse's turn.
At the DEA safe house, Huell sits on the couch as Hank and Gomez come
in to question him about the money. Hank fakes that Walt is getting
rid of anyone connected to the poisoning of a boy named Brock Cantillo
and Huell is on the hit list. He also lies that Patrick Kuby has been
missing for some time, but Huell doesn't belive that Saul Goodman
would simply allow Walt to take people out like this. Hank then shows
a fake picture of Jesse dead on the floor with his brains blown out,
which causes Huell to panic and say that he doesn't have any intel
about Walt's actions. Hank asks about the money, Huell reveals that he
and Kuby did collect the money for Walt, they put it inside seven
barrels and took them inside a van to Walt. Later, Walt returned with
a dirty van and without the barrels. Walt took a shovel from the van
and left as he and Kuby cleaned the van and returned it to the rental
agency. Hank and Gomez now have information from Huell on which van it
was and where it was rented. The two agents leave, with Hank giving a
final warning to Huell not to use his cellphone in any way and not to
leave the house for his own safety.
