I’m deadass dying at this from Venom: The Nativity, because:
» the symbiote never told Eddie they were pregnant. Eddie was having morning sickness and everything – symbiote was afraid but hoping Eddie would just notice and intuit it
» Eddie, dumb man, does not notice anything
» when the symbiote showed Spiderwoman that they were pregnant (not directly but made her feel it) Spiderwoman immediately understood, because she is not a dumb man who has no idea about pregnancy
