Hank's DEA Language Skillset?
Wouldn't a DEA agent especially one that works in a State that borders Mexico (New Mexico) and has 3 Border Crossings/Checkpoints at least try to learn Spanish especially when promoted to Assistant Special Agent in Charge and even at one time being posted to El Paso?
I thought it behooves you whether making a street bust and the criminals are speaking Spanish or you're back in the office listening to wire taps and reading other written Intelligence?
