Good find Alan!
I see the Sockpuppets have been deployed for damage control on yet another of their substantial problems. My guess is that Rossi handed Levi some material, advised him that this was from the reactor cement batch and asked him to have it analyzed. That is the most helpful way for Levi to not be totally sucked into this section of the fray. If Levi wants to own the sample acquisition himself them just say the word.
