Déjà vu

This is posted by LJ's mum.

IMO 2011 Team Singapore (photo taken last night at Changi Airport Terminal 3)

IMO 2010 Team Singapore (photo taken at Terminal 3, almost the same location). Notice Lim Jeck was shorter than Ang Yan Sheng then.

IMO 2009 Team Singapore (photo taken at same terminal, same location?). Notice how short Lim Jeck was then.

Can you find who else has appeared in all 3 photos, besides Lim Jeck?
