Once Lucas has finished choking back his urge to laugh at Miss Calculated's eagerness for quality sapient robot time, he finally starts heading back to the table as well.
Lorelei continues staring in the direction of the kitchens for a few seconds longer before realizing the other two have already left, promptly following after them once she finally notices.
Miss Calculated marches right back to their previous table without stopping, grabbing her water glass and downing half of it before setting it back in the exact same location it was previously. Jonathan, Willy, and Miss Masher were all just watching her actions quietly, their looks of curiosity clear on all three of their faces.
Well, in Willy's case, as clear as it can be, for a dog. It's more the cute little head tilt than anything else.
