Todd was helping Walt cook. I’m pretty sure he was storing it where they also stored their pest control stuff? If not, Todd knew where it was and was also a Nazi.

I figured Declan had it and Todd and Jack took it after they killed everyone.

so one thing I can't understand is how Jack's gang gets their hands on Walt's methylamene trailer he had hid in the carwash at one point? Just shows them driving around with it one episode.. did I not notice a transition somewhere? I tried to google it a bit but couldn't pin it down. I just finished my re-watch...
