Wax museum scene confusing!

Towards the end, when the female werewolf attacks the cursed siblings in the wax museum, the werewolf tossed them around like they were ragged dolls! But, the siblings are supposed to be were-wolves too, so why didn't they have equal strength as well? I mean, when sibling Jesse Eisenberg wrestled the head wrestler, he gave him a suplex like it was nothing! So, he had enhanced strength! So, he should have been on egual footing when it came to strength, with the female werewolf! Also, from what I have seen and read from wolf mythology, the female werewolf should have known that the siblings were werewolves too!? But, she didn't give any indication that she knew!? Other then these things, this was a pretty good movie!
