A month or so later…..
Stella was at the lab, as they were investigating a case. Mac noticed Stella wasn't being her normal self, even taking into account the night they had two months earlier. "Are you okay Stella?" asked mac, feeling concerned for her.
"I'm fine Mac" she responded, albeit somewhat awkwardly of course, knowing that it was next to impossible to hide her sickly state. She didn't feel much, if any energy for the last several days.
Only twenty minutes later, Mac was in the bathroom washing his face off when he heard the door open, hitting the wall and seeing Stella run to the bathroom stall, totally shocked, she either was unaware or didn't care that she accidentally ran into the men's room, kicking the stall door open before vomiting into the toilet, with her hands gripping the bowl. Bonasera vomited for roughly two-minutes into that toilet bowl, loud enough to be heard outside the bathroom, even with the door closed following the toilet flushing, several times..
She continued puking into the toilet one more time. Her face was sweating, Stella came running to the sink to wash her face off, which was now red from the sheer stress of upchucking so much stomach content. Mac, recognizing her voice, was scared for a moment, worried about dehydration due to loss of fluids.
"Stella, you need water immediately! You can die of dehydration if you don't get water immediately", obviously holding Stella gently, trying to comfort her out of hope of reducing the distress of throwing up, in addition to the embarrassment of realizing that she was in the men's room.
"What did you eat Stella?" Mac asked her, wanting to know what the problem was.
"It's not food poisoning Mac." She answered him. "No Mac. It's not food poisoning", "No, you want to know why" she told him, with a scared look in her eyes.
"I'm pregnant" she tells Mac, after working up the strength to tell him.
*Twilight Zone "Uh oh" music as we see zoom in on Mac's face as his eyes widen in suprise and shock*
