For me? You sure?
Underrated moment in Rocky. Rocky is pleasantly surprised when the guys outside the gym tell him Mickey's been looking for him.
This is another hint and how much Rocky has always craved -- but not received-- Mickey's attention.
Go back to the Dipper scene. Right before Mickey calls Rocky a tomato, Rocky is genuinely hoping (but should have known better) that Mick thinks something positive of him.
"Know what you are?"
"What?" (Said in genuinely curious tone of voice before the inevitable putdown)
"A tomato!"
"Tomato..." (Dismayed)
"That’s right. Let's face it. I run a business here, not a goddamn soup kitchen."
Note: In an older version of the script, Mickey already knew Rocky fought and won the previous night. He also knows Rocky's updated win-loss record. Rocky is surprised and delighted, especially when Mick says, "I know all my boys fights."
Even in the older scripts, Mickey is way down on Rocky and thinks he's wasted his talent. Why he would still care about Rocky's updated record isn't clear. Mick has written him off as a waste of life (in every script version) but it's still an interesting hint that Mick still cares deep inside. Just didn't fit the scene as it was filmed in the final version.
But as for Rocky, he still cares what Mick thinks. It helps set up the roller coaster of emotions in the apartment scene a little later.
