Steph's dialogue comes off as a little too 'teenaged girl' on occasion, but all in all she's decently written. She's also enthusiastic and shows initiative and this may well be the cutest Bruce-Steph interaction ever, while remaining entirely true to Bruce's character, so I'm inclined to forgiveness.
