To be honest I don't really blame Tim or Eliot, they want the kind of person they want. They may want to punch above their weight but that is their right (to want that, not necessarily to get it!)
The producers know exactly what people would like and are hoping for, and they chose to mix things up.
Also, Awhina and Adrian, she was very unhappy that Adrian couldn't say he would love her child. But he hasn't even met her son yet! He could have lied and said of course he would but he was quite blindsided.
When Adrian was giving his speech, he said he was a dad, (he went on to say he was a dad to a dog). I wonder if Awhina had any thoughts when she first heard he was a dad. If he did have a child, that might mean he would not want any more children, or that his time and his finances were diverted towards a child he already had with someone else. It's easy to want the other person to behave a certain way when we know we do not need to because those factors don't apply to us.
Yes, I think about this stuff way too much!
