Lynne talks of Tina's affair with a tattooist. At the end she talks of the actual tattoos Tina got out of the relationship. There are always perks of a relationship but they differ depending on the profession of the partner. In this case, Tina was lucky to get a discount on tattoos. She opted for a butterfly, heart and an I Love Brad Pitt. These may have all been part of the same design. The boyfriend was happy to do the heart and butterfly in a tasteful design but drew the line at the I Love... part.
