DS and I have seen him on the island twice.
Photopass pictures...
December trip, DS showing him his lightsaber LED keychain:
September trip, signing DS's book...there are pix of DS showing Jack his new light-up pirate sword, but they all have me in it and that's not fun to show:
Both times Jack was so very sweet to DS. But remember, he's a pirate, and he is allowed to act like one!
Walking around NOS in January. He barely stood still, he was walking all over, almost evading people. He was ignoring adults who were being obnoxious, even turning his back on people. You'll notice the Jacks look a bit different in the above pictures

; the January Jack was the same as the September Jack (who treated a VERY obnoxious mother in a piratey way shortly before being so sweet to my son).
In the shot below he finally acknowledged a woman who had been calling to him, following him (OK I was following too, but back at the edges just to get some pix, not to get his attention), and he kept turning his back on her...he acknowledged her by asking if she knew that she had a barnacle growing on her...she's the one with the baby-carrier straps on her back. It was quite funny.
