The actual dialogue in FFH:
"They called it the Blip. Those of us who blipped away came back the same age. But our classmates that didn't blip had grown five years older."
"When- when I blipped back to my apartment, the family that was living there was very confused. The wife thought that I was a mistress. The grandma thought that I was a ghost. It was- it was really a mess. Thank you for coming out to support those who have been displaced by the Blip. And, of course, thanks to our very own Spider-Man!"
"It's my My Blip beard. Cause I grew it. In the Blip. It's a Blip beard."
If anything, they used the verb 'blip' to refer to both the original snap and the return snap. But it's pretty obvious the intent is to describe both snaps and the entire five year period between them as that's the only way that term 'blip' even makes any sense. Plus Happy obviously didn't instantaneously grow a beard when Hulk snapped, he grew it between the snaps, aka, during the Blip.
Thank you. That is how I remembered it--I appreciate reading the actual scene.
