I felt rather early on that to really give Hani’s eventual decision to return to Kalimdor the weight and impact I desired, I needed a sufficient obstacle barring her way – a reason why she didn’t just return earlier rather than mope around in the Eastern Kingdoms feeling sorry for herself. And so I put her on a collision course with Fandral Staghem that ultimately saw her exiled, just to gain that obstacle. It’s not an easy decision she makes, but it is one she feels she must.
She can’t go alone, however – there’s more than just her in the main cast. So Te’len gets her choice to make as well – I felt that once Te’len agrees, it’s more or less implied that the remaining two will as well.
