I don't like Janna but I think if Marco liked her they would be the best fit
this extravert female <--> introvert male dynamic in relationships is wonderful in the beginning, but usually gets boring for the female after initial attraction wears off. Jackie only pretends not to be annoyed by Marco moments and does her best to help Marco but she doesn't really know what to do, Star currently likes them but she'll get bored after some time. I wonder how Janna would approach them if Marco actually respected & wanted her. Compared to other grills, she could relate cause she's most introverted grill.
