1000-lb Sisters season 4 episode 9, titled Walkin' on Eggshells, aired on TLC on Tuesday, March 14, at 9 pm ET.The episode featured Tammy's family visiting her and Caleb at the rehab facility before the wedding. The two had been dating for just three weeks and the family felt that they were moving too quickly with the wedding. They were worried that Caleb might not be released from the facility at the same time as Tammy, which meant that they would have to live alone for quite some time. Tammy's sister Amy wondered about Caleb's intentions as he had previously admitted to joining the rehab only after discovering that Tammy was admitted there. She pointed out that he could be a nice man or a "stalker."
