Relationship with Grace
Danny has been dating Grace for two years at the start of the series. Grace's best friend Will mentions that in their relationship, Danny used to be the "gardener" who tends to the "flower" which is Grace, meaning he is a devoted boyfriend. Although Grace expresses how special Danny can make her feel, Will has a different view of the relationship, saying Danny is not passionate, is passive-aggressive, and that she deserves someone more.
Following a fight, Danny decided to propose to Grace in 1998. She agrees to marry him but right before the ceremony, Grace breaks up with him (while still in her wedding dress nonetheless), mainly because of Will opinion that Danny is not good enough for her.
Danny is described as a "football-watching, steak knife-giving, I-gotta-blow-outta-here frat boy" because of his laid-back and brassy personality. During his wedding Grace admits that Danny can be childish and immature, but he is a really good and sweet guy.
- Danny appears during the pilot but his face is not seen until the season finale, marking Tom Verica's first actual appearance as Danny.
- All episodes in which Danny appears include a wedding: in Love and Marriage, he and Grace almost get married at city hall; in Object of My Rejection, Rosario and Jack get married; in Dyeing is Easy, Comedy is Hard, Danny himself finally gets married.
I forgot that to have a relationship with Grace, is to have a relationship with Will and Grace. It was always a threesome, and not the good kind. — Object of My Rejection
