That took me a while.

either its a memory of a cow or she just bit into a cooked human pattie. hopefully its a cow

Well, she said that her ability works on humans...

quickly call 911 to report a cannible

Doesn’t mean the diner knows that dead people are in its food. Could mean the meat processing plant had people fall in it

Regardless, it'd be pretty jarring to realize your burger isn't made with beef.

Honestly I would probably puke or take another bite cause that burger looks scrumptious

That cow lived a GOOD LIFE

But she said that she can experience happy memories of humans. I don't think that was a cow...

idk man that burger looks like it's implying a lot

At the very final panel, she said the ability also works on dead people. She never said anything about animals.

So who's the dead person...

Whoever was cooked into that burger. (She discovers through her ability that the diner uses human flesh instead of beef.)

Oh god x_x
