As the Sonichu comics are themselves overly long versions of the Attraction Sign, Chris intended to rope 'em in with the pitiable sight of him being cruelly tortured for daring to love.
On the whole, Chris has a parasitic dependency on pity. Not having been taught to believe in himself or cultivate anything that could've turned into a redeeming characteristic, he instead watched Bob 'n' Barb cultivate pity for themselves and for their brave autistic son, and observed that as soon as his parents said "poor Chris" to anybody, that somebody would instantly stop yelling at them and give Chris a pat on the head.
The funny thing about pity, however, is that the sympathy garnered doesn't necessarily turn into a genuine emotional connection, for any number of reasons. In Chris, Bob, 'n' Barb's case, the folks they curried favor with started asking some uncomfortable questions, and their hesitance to answer opened up more uncomfortable questions, eventually undoing all the goodwill they had fostered. Hence, the move to Chesterfield County.
