First Broken Glass

Anonymous asked: In the 50th episode, when Laura corrects Matt about Cornelius's (sp?) chopping of firewood, Taliesin mentions that it is the "first one" in 50 episodes. Was he referring perhaps to her first time correcting Matt, or the first time they'd caught Matt in a contradiction, or something else I can't think of?

Taliesin said that in reference to the glass that Liam knocked over (1:38:23) and broke after cracking up at Laura calling out Matt.
