This mod for Dragon Age: Origins contains a scene extension, primarily; it should follow, or run right after, the original funeral for the warden (an in-game scene), so that we can inject some semblance of even more sweetness, of romance into the flow. 

The scene within this mod should witness Alistair giving the warden a kiss on the lips while the latter rests on a stone bed.

Optional:

In addition to the scene extension, this mod provides clothing options, should you desire to change Alistair's and the Warden's default clothing (armor/combat gear). Trade their usual getup for finery - an ensemble for nobility. Both characters have four clothing choices each.
