In Godzilla vs. Kong (2021) movie, Walter Simmons introduces the character played by Shun Oguri as Ren Serizawa:
Walter: Walt Simmons.
Nathan: I know who you are, sir. It’s an honor.
Walter: No, the honor is mine. As is the urgency. Godzilla has never attacked us unprovoked before. These are dangerous times, Dr. Lind. Allow me to introduce our Apex chief technology officer, Mr. Ren Serizawa. He has an interesting thing to show you.
The fact that his name was mentioned just once in the entire movie was quite surprising. However his last name did catch my attention.
In the two previous Godzilla movies, Ken Watanabe played the role of Dr. Ishiro Serizawa (who sacrifices himself in Godzilla: King of Monsters to revive Godzilla).
A fan theory I read somewhere suggested that Ren is the son of the deceased Dr. Ishiro.
Is this theory true or the fact the Ren had the same the last name as Dr. Ishiro merely a coincidence?
