I know only some of these, Viki, but they are very lovely!
Bobbi kinda knows older Billy in that she has some awareness of the Young Avengers, Bobbi isn't close to Wanda or Vision (she's had to kill Vision in the past) so she kind of keeps her distance from the twins, but she does have something of a soft spot for kids either way. Bruce she'll be glad to see, if only because he's had a time of it in her world too. Bobbi and Daredevil know each other I'm sure, but I don't think they run in close circles (Bobbi is friendly with Jessica Jones and Luke Cage, she undoubtedly knows Matt at least) so that'll be interesting too.
Kenzi is always happy to throw down and hit the town! It's party o'clock all the time.
