I can see that fairly easily. Ren leaves for a while, Nora gets bored and looks at a random wall. "I don't like you Mr. Wall." Smashes the wall with Maghnild and walks away. It was a load bearing wall and the building collapses behind her without her even knowing. Thus, oblivious mass murder because of boredom.
