Oughhh yes… they couldn’t change him *back so they decided to close him away until they cant fix him. Until then they all visit, first gentle interfacing but the more they go the more rough, processor tearing raw fragging happens overtime
Sentinel would loose his mind until he forgets who he was

The primes assuming they finally fixed him, when it’s actually Senti have lost connection with reality, but they say this as an after effect of brain washing. Senti can think no more and all he wants is attention from the primes 24/7 preferably sexually. He feels alone without one of them inside him
