Groot lumbered over to Clint, placing a large hand on his shoulder and, in a thoughtful, sad tone, saying (you guessed it): "...I am Groot."
Star-Lord then walked over to Clint as well, rolling his eyes. Poor Groot... he meant well, but not too many people could understand him. "What Groot's trying to say is... Rocket's not normally this, well.. irrational. He and Six apparently went through something really traumatic together, and they've developed a cute, weird, and quite possibly unhealthy dependency on each other. Without her here.... it's like putting someone up on a tightrope then yanking away the safety net with no warning."
