I also would complete on 3rd hoping to get it HU with Seat 1. But, regardless of likely being ahead at this point, if I get 4 callers, the hand now looks unappealing. The raise did not work.

Given your completion, 8A8A rises to mind in the more suspicious. I might bet 3rd and proceed with caution. Who knows? Maybe it'll end up between you and Seat 1 after all. Also, you could be in worse shape. Loss of the 6 is bad but you did improve kicker-wise. Diamonds and spades could be scary but there are relatively many out.
Fold to any raise.
