I didn't read that post. I was going by what was claimed by the wife in the dialogue in the end of the post above. In that post the husband doesn't seem to challenge the claim made by the wife that the substance put in his water bottles was potassium, so I assumed that the claim was probably true. If it wasn't, then obviously what I say above is irrelevant since it's all premised on the substance being potassium.
