At the moment, Harriet was indeed one of Meesei's primary suspects, but she was careful not to show the extent of her suspicion, as she felt it was best to keep as much of the current status of the investigation a secret as possible. The only exception would be if she could safely exonerate any of the lieutenants, as they could be more helpful to her if they knew they were no longer suspects. Harriet was possibly the traitor, but Vera still could not be absolved of suspicion. She did take note that Vera seemed nervous, but given her relationship with Jerrick, those outward signals could also be attributed to grief. All of the lieutenants agreed that Oswall and Darahil had left without touching the waterskin, but so far, Meesei only had Vera's word that Harriet had been left alone with the waterskin. There was the possibility that Vera was lying, so without more information, Meesei could not yet make a judgment. 

"If the waterskin was poisoned at the meeting, then it is a possibility, but there are other incidents I need to consider." Meesei answered. "Moving on to after the meeting, I have gathered that all of the lieutenants separated to their own tasks, apart from dinner, at which Jerrick was not present. After Jerrick informed me of what was to come, we made our plans for the ambush that night. I know what he was doing after the meeting, but not exactly where he went. If you can remember anything at all about his movements, after the meeting, it could be useful. Beyond that, I also need to confirm the alibis of each lieutenant after the meeting. Not only do I need to know if there is anyone or anything that can prove where you were, but I would also like to know if there is anything that could prove to me where the others were."
