Premise: Diaz points out that ephedrine is also a main ingredient in Metabolife, though he duly notes Ellis' claim that this is mere coincidence (he fails, however, to repeat Ellis' assertion, apparently backed up by DEA- and FDA-certified labs, that you can't actually make methamphetamine out of Metabolife).

Hypothesis: Diaz is angry because their assertion that ephedrine is a main ingredient in Metabolife, is not being properly listened by Ellis.
Relation: neutral
