Ian has 3 children from various marriages. He doesn’t have primary custody of any of them besides you, his youngest. He has primary custody of you due to the fact your mother just left you on his doorstep when you were 3. He. Had to get you into therapy since you had developed an intense fear of being abandoned and separation anxiety.

So when he was chosen as a consultant by Donald to analyze any faults in the park whilst on a tour, he was hesitant. You’re 12 so he could technically leave you with his brother. But He really didn’t wanna leave you not even for the 3 days, but at the same time he has to go. A park with live dinosaurs sounds dangerous. So he just ops to bring you with him.

In the helicopter he’s chatting it up and doing his usual Chaos spiel whilst getting on Dr. Grant’s nerves by flirting with his partner Dr. Sattler. John Hammond, the director/founder of the park is also getting annoyed at him. Later on once they get to the park they also meet John’s grandchildren Lex and Tim. Tim is chatting Alan Grant’s ears off and it amuses Ian.
