Reading between the lines, Isaboy and Slingblade have been at odds with each other (probably because Slingblade is sexually frustrated because Phil is too scared of sex and can't give Jon #analrips due to Phil's acorn dick/shemale surgery) and their relationship has soured. He's also sick of Phil's typical bullshit (Kiwi Farms, Antifag Supersoaker, Latinx, stink ditch lies, etc.). Slingblade goes looking for another mongoloid to mooch off of and get his geriatric jollies off. Someone agrees to keep Toren well stocked in vodka and internet service, and may or may not have agreed to the other thing. Slingblade tells Isaboy that he's leaving for greener pastures in a month and a half. Phil posts a bunch of bullshit about how being Antfag Supersoaker has made it impossible to support the Vodka Ogre and a bunch of other bullshit to make it seem like this was a mutual thing, but in reality he's terrified of the prospect of living alone because Kiwi Farms. A short time later Slingblade finds out that his new mooch mark as changed his mind and he has no place to go. He then begs Phil to let him stay, possibly promising Phil things he never intends to deliver (I'll pay for my own booze, I'll help with the rent and bills, I'll kill those evil Kiwis for you, etc.) because he doesn't want to be on the streets. Isaboy accepts and is relieved that he still has his attack ogre to set on anyone who tries to break in and rape him.
Have I got this right? I feel that's likely how it went down.
