Doesn't matter his state. You can only determine intent. You cannot determine success as both pc's are mine, once again edit
First, Sakura is a non-entity in this, she's in no state to even resist by your own admission.
Second, I'll change it to intent, and trust me, Connor won't like being on the receiving end of a Hunger Frenzy.
Thirdly, Frenzy literally makes a vampire stronger, faster, and in general far far deadlier. Jack's now intent on one thing, feeding, and he'll take any source he can get, but due to EX charisma, congrats, Sakura is the target. Jack can pretty much blow by Connor without much effort on this end.
