Buchan
has whacked the hammer to Roswell
My reading was that he hadn't convinced him of it, he just convinced him to hear Jesse out. That's why after Jesse confessed Hank asked Gomez "Do you believe him?" and Gomez said "Unfortunately, I do" (or words to that effect).
Yeah, it was obvious that Gomie was yet to be convinced. However, how did Hank convince Gomie to be in that room in the first place? Did he invite him around for a few Schraderbrau and magically dump Jesse and a camcorder on him instead? "You know that Heisenberg lad that I'm obsessed with? Well our friends Jesse may just know who that is..."
Ridiculous. That scene should have been crucial to understanding how fecked Hank was/is with Walt's confession tape. It would have been good to see Hank try to convince Gomez with the facts he had at hand and to see Gomez's reaction. Might Gomez have been suspicious of Hank? His behaviour in the last few weeks/months has been erratic to say the least. Gomez may well have had a 'Hank special' and had a "Eureka!" moment with minimal evidence and only suspicious behaviour to go on. Instead we're treated to a smiling Gomez with that glorious Latino goatee settling in for an interrogation of Jesse with absolutely no explanation as to how we got there.
