With Gabi and Luke being practically inseparable, they really were 'like father like daughter'. They'd always done things together, for Luke was her only parent, and they told each other everything.
Or if it wasn't to to each other, it would be to Cal, Mike, or Ash, who had been with them since the start too.
But as the pair explored their own love life, and Gabi's health took a turn for the worse, the pair found themselves having more differences than every before.
And that was something new for them that they didn't know how to deal with.
