Though people on here have assumed that he is timid, I assure you that is not the case. Lucas has an explosive temper, especially regarding males he thinks may be gay. For example, he perceived another homeless man, who happened to be sitting next to him on the bus, to be gay. The man brushed his shoulder and Lucas exploded into a tirade about he isn't gay and to respect his personal space. He was escorted off of the bus by police. He also has many issues with women, OBVIOUSLY (Lucas also has no contact orders against him that he likes to violate. I wonder why.) and since there are women in authoritative positions within the shelter, women who help with feeding them, counselors, etc. that could have also been a problem. (Tie that in with it being a Christian organization when he is vehemently against religion/a sperging atheist) I'm sure he had a homophobic/misogynistic fit in the homeless shelter which led to his banning. That's only speculation, though. Sorry.
