Why the long face (read: could you explain the PF 3-bet)?

TT has equity against lots of starting hands. we are likely to get it HU with pf-raiser, who most likely has unpaired big cards. So it is ~70% for the flop to miss him, and we have some fold equity when he checks to us on a missed flop. We can fairly easily muck if the flop hits him *ahem*.
