Only the front door is LOCKED, so he has to ring the doorbell, and eventually the door swings open on Brendon, Bogart in his arms, and he looks Spencer up and down, and smirks.

"I'm not interested in whatever you're selling." Which is a total LIE, because Spencer's pretty sure that Brendon had been ready to beg for him before they got interrupted. Spencer's annoyed, because he was sexually frustrated, guilty, and now he's RUINED a pair of perfectly good shoes, so he just crowds into Brendon's space until Brendon backs up and lets him into the house.
