WMG / The Boss Baby: Family Business

Carol knows about BabyCorp.

At the end of the movie, she answers Tina’s phone and apparently goes along with whatever the Boss Babies are telling her. Presumably in her own childhood, Carol’s hypothetical sister may have been a Boss Baby and took her on their own crazy adventure. A potential third movie will have Carol reveal this to Tim, and now that Tabitha knows the truth about Boss Babies, the whole Templeton family will be involved in the next adventure. Carol will invite her sister, whom Ted will fall for and possibly make him consider having his own kids.
