Rina

Rina is Joe and Walter's birth mom.

History
Rina was pregnant and trying to choose between Joe and Walter and another couple to adopt the baby. She'd had no prenatal care, so Joe and Walter brought her to Addison Forbes Montgomery, who did an ultrasound, which revealed that she was pregnant with twins, which she didn't know. During the exam, she complained of heartburn, so Addison gave her an antacid.

Walter took her to the bus station to go home, but she started having severe chest pain, so he brought her back to the bar where she collapsed and had to be taken to the ER. ("Testing 1-2-3")
