Blood really is thicker than water. Teresa Giudice opens up to brother Joe Gorga about her worries as husband Joe Giudice prepares to leave for prison, as seen in Us Weekly’s exclusive sneak peek of The Real Housewives of New Jersey's episode airing on Sunday, October 9.

In the clip, Gorga arrives at his sister’s home with food (obviously), and takes full advantage of the alone time they get with Joe Giudice out for the afternoon and Teresa’s daughters — Gia, Gabriella, Milania and Audriana — at school.

Gorga, 37, dives straight into the deep end with, “How do you feel, like when he goes? What are you worried about?”

“I think about the fights and stuff in there. Because I just feel like guys, right away they lose their temper. I told him, you know, just be careful of who you deal with,” Teresa, 44, replies, indicating that the Turning the Tables author was passing along “camp” tips to her husband before his March 2016 surrender. (Teresa returned home in December after serving an 11-month stint in prison for fraud charges.)

Gorga keeps the conversation moving by admitting that he and their father — who Teresa has an extremely close relationship with — were “mad at Joe” during his and Teresa’s trial more than a year earlier. Then he point-blank asks the question on everyone’s mind, "Were you bitter at Joe?"

"I was mad that I got stuck with being involved,” Teresa reveals. Cue the dramatic music. “Yes, I should’ve made sure everything on those papers were correct before signing them, but nothing was done intentionally. You know? We trusted the wrong people.”

And just when you thought this clip couldn’t get any better, it does.

While Teresa talks about her close relationship with her brother, we see an old clip of the siblings dancing at a formal gathering. And Gorga moves and looks exactly the same as we know him to today … but with a full head of hair!

See for yourself in the clip above and watch The Real Housewives of New Jersey on Bravo Sundays at 8 p.m. ET.
