Neville had been talking about the Calendula, trying to take Millicent's mind off of worrying over Ella and put it on something else when his voice trailed off and in his periferal vision, he saw Millicent reeling and then...
"Oh bloody hell..." She reached out for him and he caught her arms, seeming to try and calm him down but ruefully, he'd seen this when Katie and George got worse. Neville was holding her up with one arm and he would've gotten his handkerchief out but, it wouldn't have stopped any of the bleeding... they learned that the hard way.
"Millicent.... come on.. dammit..." She went limp and Neville picked her up, carrying her over to where he could set her down comfortably and laid her head down. With all the confusion and uncertainty over this illness, Neville had prepared himself a few days beforehand and made himself a portkey to the shack.
Taking out his every day pocketwatch, he pressed it to Millicent's palm and her thumb on the trigger to open the face-cover, just under his thumb. He slipped his other arm around her shoulders and situated her into more of a sitting position, pressing the button on the watch and they were transported to the shack.
