Was I the only one who thought Walt's last-second intervention was a little too deus ex machina?
I didn't think it was. Walt heard the report on the TV -- which was unsurprising, as Skylar said it had been on all day -- and immediately knew Jesse would be pushed over the edge. The best place to go looking for Jesse would be that corner, as those dealers were always there. If Jesse wasn't there (yet), Walt could either wait for him or go looking for him.
