User blog:Greater good/Lorcan and Lysander in DH2?

I was watching Harry Potter and the Deathly Hallows: Part 2, and in the epilogue I spotted these twin boys. They can be seen off to the right when we see the Malfoys.

I think they may be Lorcan and Lysander Scamander, sons of  Rolf and  Luna Scamander. Jo said they are younger than the children of Luna's friends, which these boys are. They're also blond, like Luna.

Any thoughts?
