I've ALWAYS doubted his story. Part of me thinks he must have thrown the glass at Suzanne. Or hit her. We all remember the way he reacted when someone in the livestream suggested he was a pedo; he spit on his own phone, and was ready to punch his own phone. I don't see Lucas having the willpower to direct his anger purely at an inanimate object, when the source of his anger is right in front of him. If I remember correctly,
@QueenBurritoSupreme said that he had manhandled Daniel, when Daniel was unhappy with the fact that Lucas was a complete slob as a roommate, and was eating all of his food at night rather than sleeping.
Also, I don't see how he would get a DV, rather than a disorderly conduct for throwing a glass at a wall.
According to Cyril, he got extremely violent when people disagreed with him. Cyril ended their relationship after Lucas laid hands on him after Cyril insisted he was an agnostic rather than an atheist.
I could easily see a disagreement about young women between him and Suzanne leading to him putting hands on her. To me, this makes much more sense in terms of his DV.
We all know that Lucas is a coward, but that doesn't mean that when he's angry enough, and when the person he's angry at is physically smaller than him or weaker than him, that he wouldn't get physical with them. By his own admission he slapped his brother in the face, for his brother not giving Lucas the credit for initiating the relationship he had with his girlfriend.
