Short stack calling 2 all-ins with TT?

$65 Paris 9:30am tournament and we're down to 6 players. Top 3 get paid and the blinds are at T400, going to T800 in 5 minutes. Short-stacked 2nd position goes all-in for T2000. Small blind has about T10-12K and calls the all-in. In the big blind, I have 2400 and have pocket tens. There is one other big stack, a medium stack of about T4-6K, and one short stack less than T2000. What to do, all-in or fold, with these generic facts? I'll have some an orbit before getting hit with the 800 blind, but I need a spot to shove soon.

My read on the first all-in was that he had small pocket pairs. He had called with big hands earlier and made a small raise with AK. He did not look like he wanted a call and was somewhat deflated when the small blind called.

Small blind was a good player. No solid read but I felt his range here was pretty wide. I was thinking almost any suited Ax or 2 face cards on up. If I trust my reads, what's the play? Is my range on the small blind too big or small?
