It’s totally consistent with him in movie 1, too. Like it’s so clear that his entire experience of her is “….oh wow this woman. She’s so amazing. She just gets more amazing. Oh, oh wow. Maybe like I could stay with her. How do I make her like me. I KNOW I WILL STEAL HER A SET OF ARCHEOLOGY TOOLS. SHE LOVES ARCHEOLOGY. YEAH GO RICK.”
And by movie 2 it’s obvious he’s spent the past however many years living a life of “omg am married. TO EVIE. I have a wife. EVIE IS MY WIFE. OH JESUS I HAVE A KID. :D :D I HAVE A FAMILY AND A LIFE. WITH EVIE. WHO IS MY WIFE.”
Interspersed with “why is my wife trying to get us killed. Why is my son trying to get us killed. Or at least himself killed. JONATHAN WHAT YOU DO. Evie no. Evie love of my life no. EVIE. ALEX!! OH FOR FUCK’S SAKE! JONATHAN!!! Why does everyone I love have the self-preservation instincts of SOMETHING THAT HAS NO SELF-PRESERVATION INSTINCTS?!”
