So it seems Puck messed up... He was supposed to put some flower stuff on Demetrius so he would love Helena, but instead he put it on Lysander... And now both Demetrius and Lysander are doting over her and fighting with each other. And its a bit chaotic since Helena thinks the two are messing with her, and Hermia is mad about it. Good thing they dont know it was Puck... And now, Oberon is watching it go down with Puck.

Oberon: this is negligence... Puck: I may have... Mistook..?
