I've been a lurker for YEARS here, so I decided to make an account to shed some light on some stuff from having Wern encounters (initiated by him, I blocked him after a while). Even before the Starbucks event, I knew of his antics.
Unsurprising by all, Lucas' family has cut him off. No one will even talk to him after they found out about him wanting to fuck his niece. I don't know if they are aware of his recent bout of homelessness, but if they are, they won't help him.
The reason why his mother went to Spokane to get him committed was because someone sent her screen shots of the convo with the girl in VA. From him telling her to make her "pushy squirt" to talking about his niece, his mother was shown everything. She defended him saying he's mentally ill and the girl in VA was bullying him at first. They said if she doesn't do anything they're gonna take them to the Spokane Police. Within that week she went to Spokane and he went away.
When he went to college he smelled so bad students moved away from him and was so creeped out by him that they went to the teacher to ask to talk with him. I don't know if that happened, but given the reason for the convo, Lucas would ever admit it.
He was purposefully avoided at the campus because of his infamy. Freshman kids were warned of him by basically everyone.
So.....basically what we thought would happen, has happened.
