Secondly, a comic title which is serial, has absolutely nothing to keep it from having a soulmate or love interest especially since serial.
Thirdly, in television and radio programming specifically, a serial has a continuing plot that unfolds in a sequential episode-by-episode fashion which is directly counter whatever stupid argument you were trying to make.
Fourthly, I believe the term you were looking for would be "episodic" which comic books aren't, as a medium. Comic strips, perhaps, comic books, no.
