I am going to write a minor spoiler for Caerus Residential here, because I don't think you are going to get this chance in your next playthrough. It is up to you, but I suggest you read it when you are ready to leave Caerus.
Don't forget to walk around in the shafts.
You meant Vasilica? Kind of underwhelming tbh, wish they'd given him dialogue. After those cool text messengers have an old man shout randomized taunts at me during a short gun battle wasn't exactly epic.
