The first of many big revelations in She-Hulk: Attorney at Law is the revelation that while Bruce Banner was chilling in Mexico post-Blip in order to re-establish himself and unite his two conflicting halves, he and Tony Stark erected an outdoor bar together. Its a minor detail in a larger conversation, but it does give a little hint to a familiar bond that once existed within the Marvel Cinematic Universe.
Once upon a time, Marvel fans dreamed of a world where all of Earth's mightiest characters hung out and favs each other. For some reason, Clint lived in the vents. It was a simpler time.
The friendship between Tony Stark and Bruce Banner was one of the most well-known characters in the Marvel Cinematic Universe. It was so popular that even Robert Downey Jr. and Mark Ruffalo recognized it.
The later MCU movies drew their fan base. Not necessarily because the two characters no longer spoke, but because the MCU became a juggernaut of a million moving parts and characters that needed to be strategically placed like chess pieces in order to get the next plot point. The MCU began to suffer, and for those who enjoyed the unexpected friendships between these unlikely heroes who wanted a full scene of the post-Battle of New York shawarma lunch, the next one would follow suit and completely undermine
Clint randomly got a family in the second Avengers film, and Natasha had an out-of-the-blue crush on Bruce (at least She-Hulk acknowledged how bizarre this part was). After spending all of Captain America: The Winter Soldier hunting for his best friend Bucky Barnes and then going against international law, Steve Rogers decided to go back in time and live his entire life without Bucky, despite the fact that while he raised a family with Peggy in this timeline, Soviet agents tortured him.
Future Science Bros bonding will not be possible in a post-Endgame MCU because Tony Stark is gone. But this small acknowledgment is a little reminder that once upon a time, the Avengers were able to get along and liked each other on screen. But, maybe with more space on Disney Plus, we may finally see more of this emotional connection that fans longed for in the first place.
