Peri’s activation noise is a noise of happy suprise, because she apparently is so enamored with me that she is always overjoyed to see me no matter what. Rufus’s activation noise is him groaning because I woke him up.
I actually noticed that too, looking at all of them, all but one is an adaptation or sequel or a remake.
I’m at a US military base in the Eastern hemisphere so it’s absolutely too late for us here.
