展開によっては is a fragment that doesn't say a lot by itself, more context is required. I could translate it to something along the lines of "Depending on your progress...", which can mean a lot of things. Obtaining her as reward for "getting that far" (i.e. reaching/clearing a certain map) is one possibility.

I went through the Japanese comments and noticed that even they aren't sure what's meant by 展開によっては because the OP didn't post the interview in its entirety.
