The Pittfest is a time loop but only for Robby.
The first loop made him think he had some dream that came true and now he was re-living it in real time.
Then it happened again. This wasn't normal. He called the police and said there will be a shooter at the festival, they didn't believe him. It happened all again.
At the fifth time he stopped trying to get the police involved and tried to make sure Leah wouldn't go there. Three times he made sure that Jack and his girlfriend weren't at the Festival and yet every time she died for a different reason. But died.
The sibling tried every time to prolong their father's life and it hurt Robby the same way with each loop.
He stopped Dana from being hit. But when he did, another person got the hit or Danna fell over.
The kids died, the parents cried.
Why was he even in this loop when nothing could be changed? What was he missing?
What also never changed was Whitaker finding him at the lowest moment. He changed places for his panic attacks but Dennis still somehow found him. It was also a part of the loop.
At first he thought: how cute, does this boy think he can help me?
But after probably the 50th loop or more it changed. He started to look for Dennis, hoping the boy would find him. Every panic attack he was looking for that boy: will you come to me again? Let me hold your hand?
Was it already two months of the same day? Three? The man didn't know and started to care less. Why try when the same day will come again? Why?
All he needed was Dennis by his side, the sweet boy who looked scared and didn't even know the day was on repeat.
There were some loops, where the first thing he did was hug Dennis to welcome him. Confusing everyone even the boy. Mostly the boy.
One time he went to Frank and told him at the start of the day to fuck off and go to rehab, or days were he told Santos he knew and didn't care.
Why? He could correct it on the next loop.
One time he even kissed Dennis, got into an HR nightmare but the next day everyone forgot about it. He liked that loop.
He was tired, relieving the same deaths over and over again.
There was a loop where he told everything to Dennis. The loop, his obsession and the boy maybe didn't believe him, but still was so soft and welcoming. He recalled at the end of the day Dennis leaving him his number before he left with Santos with whom he was living.
So again he tried to repeat the first one, the original time. Looked forward to Dennis helping him. And for some reason, at the end of the shift he didn't go to the rooftop or to the park. He thought that maybe it was possible to take Dennis home, maybe fall asleep with him with the sad knowledge he would wake up alone.
Where the fuck was Dennis going? He went after him to find him in the 8th floor.
He was living there through all the loops? And Robby didn't see that? Wasn't he living with Santos? Maybe in all the loops Santos was the one who found him?
He offered him a place to sleep at his home, Dennis didn't want to take it but Robby just said: you help me let me help you.
The next day Robby woke up knowing it would be the same, but in the end he would take Dennis home again. And again.
He went to the kitchen and there he was. Dennis.
Robby screamed in suprise and asked him what the fuck was he doing here. Dennis was confused and asked if the man forgot that he found him on the 8th floor the day before and offered a place to sleep.
Robby was free from the loop. Why? He didn't know but was sure it was all Dennis doing.
He hugged the boy as he did before, not that Dennis would remember the times.
It was a new day at the Pitt and Robby couldn't be more happy. Maybe not that much since Santos turned to be a patient, hit by a car but nothing bad happened to her. Broken arm and a light concussion. There was another guy who also was hit, but died. He looked at Dennis and it hit him. He would go with Santos home, he would be with her.
Dennis probably died every time he went home with Santos. Every loop. And Robby didn't even know.
This was the reason for the loops, he was meant to rescue Dennis. Another person died in his place, but Robby was too traumatized and obsessed with Dennis to care.
