This is just a little something I recalled from the last time I watched Beauty Marked. It’s safe to assume that the bow came from Dora’s kingdom and Danny and Tucker didn’t have any time to make adjustments. Real bows are not easy to pull back to your ear like you’re supposed to, much less well behind your head like Tucker’s doing. I can only imagine how much more difficult it would be when you aren’t using an arrow.
Conclusion: Tucker is strong as hell.
(Also, he’s using his left hand to pull, which means he’s either left-handed or, the more likely option since only 10% of the population is left-handed, he put on the gear wrong and is using his non-dominant hand, which makes this shot even more badass.)
