I know they like to show Walter as a older man who is a mental unstable genius, and some of the things he do is humorous, but having him eat liquorice while performing an autopsy with bloodied hands, took the cake!
When Peter was showing the new female fbi agent the fringe division in the basement of a Harvard school building, he walks through the door like it is some big government cover up conspiracy-only for her to be greeted by a regular school lab with only two people working in civilian clothes. I thought it to be funny!
One of the most concerning inconsistencies in this episode was with Charlie. During the time in the hospital basement, the shapeshifter(nurse) seem to have taken over Charlie's body and swapped clothes in less time it takes Peter and the fbi agent to get to the scene to see Charlie and the dead nurse. Its funny because earlier it shows that process taking some time without the clothes changing part. Then on top of that, you see the shapeshifter(Charlie) dumping the real Charlie's body in the furnace. Now, wouldn't that require three bodies total? You have the shapeshifter(Charlie) and the nurse, and I'm sure the nurse went to the morg. So where did the extra body come from?
