The fall, sacrifice and remain

After seeing the script, my thought circle around the concept of D losing some of his part along with Pax too. I depicted it as his cog less miner version falling alongside Pax which fades away when Primus take turn. It's hurt me so much. I lowkey delusional that the part that vanished is with Optimus, that's why he kept on having hope that his friend one day will come back to him for a million of year.
