Well I would assume this is his range:

K8, 85, T8, 88.

85 and T8 are 15 combos total.
K8 and 88 are 9 combos total.

Of all these K8 would be discounted the most with no flop raise so it's close to breakeven if you call a cap. It's a definite 3-bet if you'd never fold the best hand to a cap.

edit: fixed combos.
