The ratings were lower from the previous week - and you could b right about basketball impacting the ratings - but they were on par with the season average. So, a good news/bad news scenario.
Yeah, I wish we had a better idea as to why Tina's marriage fell apart. Did her feelings for Ty cause her to distance herself from her husband? More likely, they were growing apart and, as it happened, she was drawn to Ty and then the affair occurred. But how deep are her feelings for Ty? Was he there at a time when she needed someone and so she thinks she's in love with him or is he really THE partner for her?
I also found it a bit odd that we didn't at least get a mention of her husband. They are still married so, by law, he could have the right to make medical decisions for her if she were unable to make them for herself, depending on what her medical directives are. I can understand not having time for scenes with the character/actor, but at least say he's out of town on business and is making his way back.
