So, Charlie is like really happy that Alan finally moved out, and then he says he'll ocntinue to come here to have sex with Melissa. So Charlie tell him to do the wise thing and dump Melissa & keep Lyndsey. So he breaks up with her by phone.
Later Melissa shows up to kick Alan's crotch but charlie tells him he is not there, so she kicks his crotch. He givesd her his address by she never appears again... (maybe car killed her). So meanwhile Alan is in his new house acting like Bill Cosby and then he accidentally leaves his pipe on a place were the drapes (and letar, the house) end up on fire. The episode ends with Lyndsey, Eldritch, Jake & Alan going to live at Charlie's.
Title reference: Alan, describing Charlie. Saying he is prickly in the outside, but soft in the inside.
Overall: Good. The best of the episode was the cliffhanger-y ending. 8/10.
