In one respect it was a blessing Karin Murphy never lived long enough to see one of the ‘Little Folk’ tower over her at 5 feet, 1/2 inch.
Lacuna is a shade behibd in height and the rest of the Za Guard just behind her. The auxiliaries all probably will grow a little as well but less so.
Toot will or should have grown considerably after Battle Ground, Harry’s relationship and control over the Little Folk will have grown considerably following the events at the Castle, and the role he had in taking out the Titan. The Supernatural world by and large didn’t consider him to be a nuclear power, which he has been since acquiring Demonreach, but they presume he has the Eye, so now they do.
Given his increasing size, Toots voice should be on the verge or breaking and deepening in forthcoming portrayals, Jim should consider this JUST to torment James Marsters.
