Venom (2018)

Continuity mistake: When Anne breaks up with Eddie on the sidewalk right after they get fired from their jobs, she approaches him and drops the box she is carrying. A ceramic mug falls out of the box. There is both visual and audible confirmation. After putting her ring in his shirt pocket, she bends to pick up the empty box and proceeds to walk away without also retrieving the missing contents. (00:14:45)

Venom: You come in here again, in fact, you go anywhere in this city preying on innocent people and we will find you and eat both your arms and then both of your legs and then we will eat your face right off your head. Do you understand?
Robber: Please.
Venom: Yes. So, you will be this armless, legless, faceless thing, won't you? Rolling down the street, like a turd in the wind. Do you feel me?
Robber: What the hell are you?
[Venom's face partially opens to reveal Eddie's face]
Eddie/Venom: We...are Venom.
[Venom's face fully reforms]
Venom: On second thought.
Robber: Please.
[Venom kills the robber].

Trivia: When Eddie walks into Mrs. Chen's store, Eddie asks Venom what he would like to eat. Venom responds that he wants tater tots and chocolate. In Venom: The Hunger, it's discovered that the symbiotes need a chemical called phenethylamine to survive. This chemical can be found in both brains and in chocolate.

Question: When Eddie goes to see Dan about the test results, Dan says that the symbiote is damaging Eddie's organs but Venom says it's part of the symbiosis. Was Venom really damaging Eddie's body? If not, what was he really doing?
