User blog comment:Chaos Red/Evidence Of Seddie Being Canon After The Story Arc/@comment-3553219-20110615022225

I think the fact that Sam is in heels is probably the biggest clue of all. They only put her in heels for a reason. In iSam's Mom it was so the slightly short Jennette could do scenes with the very tall Jane Lynch, iMake Sam Girlier it was very specific to her new personality, and every other time it was for an event (the iCarly awards or the pageant). If she is in heels now than its probably to make Seddie scenes with Jennette and Nathan easier for both of them.
