This is the first time we've seen Drew even display the slightest of face tendencies, so its hard for me to say, honestly. But for speculation's sake.
Drew needs to be repackaged, thats for sure. The "Chosen One" gimmick has gotten old, and fast. Even the references to it make me cringe as I realize how far his stock has fallen since being given that label a year ago. So giving him something outside of the ring to be involved in, such as a backstage angle, may be something to explore. Its not that they ever acknowledged on-screen that Tiffany was Drew's wife, so having him "get to know" Kelly as a nice guy while having him be as vicious as ever within the ring is certainly an avenue worth going down.
I think the whole situation last night was very indicative of a turn, even if its into a tweener like character. I liked that he added the line that the person you saw in the ring wasn't the same person he is outside of it. It gave him something to connect, something hes been missing for a long time, and that's been a personality. Sure, pairing together couple's has been a disaster more often then not, but that's been due to bad booking more then anything. I think its entirely possible to book this correctly, and could be a turning point in Drew's career if the face character connects with fans. That's something he's been lacking his entire career has been said connection. Kelly, despite her utter ineptitude in the ring and on the mic, has said connection.
So Im interersted, at least, into where they go with this situation. I hope this wasn't a one week situation, and Drew continues to pursue Kelly with his "different people" mentality, and it pays off for Drew. The mid-card on Smackdown is heel heavy and short of faces, so an effective turn for Drew could be a plus not only for him, but for Smackdown in general.
