First video: Kevin, Michelle, and Lydia from BB 11 are bowling and hanging out. Michelle introduces herself from BB 11 to some strangers who are baffled. Interesting side-note: Joe from BB 8 is also bowling.
Second video: perhaps more amazing Ronnie, Michelle, and Lydia are having adventures together.
It boggles my mind that some of these people could hang out. Kevin evicted Michelle, Lydia and Michelle hated each other in the house, and Ronnie once called Michelle on live TV "the worst human being I have ever had the misfortune of meeting". Amazing that they could all hang out.
