its still the same strawman basically. dipper and wendy are both high schoolers by the time the series ends. also, keep in mind that we see that wendy is sort of an outcast in her school anyway so its not like she has any popular image to maintain by only dating pre-med college chads instead of a high school freshmen.
comparing all that to being a near-teen hooking up with a toddler on a tricycle is just alex's retarded "poptarts and pokemon" morality. it was a fun moment in the episode, but the message behind it was dumb, just like pacifica's pony joke in the finale.>Stop listening to your intrusive thoughts, everything in the world isn't about people hating you.
where the hell did you even get this from, well besides maybe a fortune cookie
