What are some quotes in To Kill A Mockingbird that show love connections between characters.Example; Boo and the kids , "Summer , and he watched...

It looks like you have some excellent examples already,
but here are a few others from To Kill a
Mockingbird.

UNCLE
JACK.  Everyone seemed to love Atticus' brother, the doctor from
Boston.

•  
  
  • Rose
    Aylmer was Uncle Jack's cat. She was a beautiful yellow female Uncle Jack said was one
    of the few women he could stand permanently.
  
  
  • I always
    thought it was funny when Uncle Jack pecked Atticus on the cheek; they were the only two
    men we ever saw kiss each other.
  
  
  • "I shall never marry,
    Atticus... I might have
    children."
  
  

MISS
MAUDIE.  Maudie has a certain love for Jack, too, at least in a
flirtatious sense. Each Christmas the two old friends trade insults and Jack always
repeats his request for her to marry him, but Jack claims that he is only "trying to get
Miss Maudie's
goat."

•  
  
  • "Call a
    little louder, Jack Finch, and they'll hear you at the post office, I haven't heard you
    yet."
  
  
  • She loved everything that grew in God's earth, even
    the
    weeds.
  
  

DILL
& SCOUT.  Despite their youth, the
two hope to marry some day--though Scout's violent streak may have eventually deterred
Dill anyway. 

•  
  
  • He
    had asked me earlier in the summer to marry him, then he promptly forgot about it. He
    staked me out, marked as his property, said I was the only girl he would ever love, then
    he neglected me. I beat him up twice but it did no good, he only grew closer to
    Jem.
