Henderson and THEresa

So on Mondays’ episode when Theresa came to the mansion to tell Brady about her supposed pregnancy she was announced by Henderson.  I am not sure if this was deliberate or not but he pronounced the "H" in her name.  I rewatched it several times.  Was he mocking her or was it just a mistake or is Henderson joining the ranks of stupid Salemites who cannot pronounce such a common name?  I mean Daniel insists on pronouncing it "Treeesah"!
