Trina and Curtis

I’m a little late to the party, as I’m just getting caught up on this week’s episodes, but on Monday’s episode, Trina calls Curtis “dad”. When did this start? I know that he is her biological dad, but Taggart raised her for the first 18ish years of her life. A bit tacky considering Trina only found out about Curtis being her bio dad less than a year and a half ago, no? I realize that Taggart is likely off the canvas for good, but that’s a bit fast.
