Let's clear the air:
Eva Harris will be having lunch with Seymour that Sunday. She happens to be in LA then for a conference. We don't know what kind of conference or what, if anything, she will be doing at it. It could be business related, it could be something else entirely. We just don't know.
That's it, no more, no less. Anything beyond that is pure speculation.
I suspect that the speculation is fueled by a desire to see some results from the Dengue tests. To suggest that Seymour is dropping hints is ludicrous. To suggest Harris will be presenting Dengue results on a Sunday in Los Angeles is equally untenable.
