Tod lives in a modest apartment building called San Bernardino Arms. He walks up to his third floor apartment but pauses on the second floor because someone named Faye Greener lives there.
There's a promotional card stuck in Tod's door from Honest Abe Kusich with an incomprehensible message scribbled on the back. Because this is making so much sense so far.
Tod actually knows Abe—sometimes he even paints him, as he does Faye and her father Harry.
Tod met Abe when he was living in a hotel called "the Chateau Mirabella" (2.13). Returning home one day, he stumbled across a mess of blankets in the hallway that he assumed to be covering a small dog.
The blankets were actually covering a dwarf. An angry, mostly naked dwarf, no less. This dwarf had apparently been kicked out of his lady's apartment while still in his birthday suit.
Tod knocked on the woman's door and managed to get Abe's clothes. Abe was off-putting and hostile, but Tod eventually learned that this was just the guy's personality.
Tod and Abe ran into each other a few days later, and Tod told Abe that he was looking for a new place. Abe demanded that Tod move into his apartment complex: San Bernardino Arms.
Though hesitant, Tod signed on the dotted line as soon as "he saw Faye Greener in the hall" (2.83).
