Not enough film to answer the following questions and intire film may not answer them all:
Did wimple put a BB into you at any time during the sortie?
Did you stress your wings earlier and finish them off in the loop after wimple put a BB into you? This I have done before. More than once

Could there have been a packet or two delayed on either your or someone's end whom damaged you enough for an assist and wimple got the kill due to damage dealt earlier? <<< Vary unlikely and impossible to answer on my end, but I suspect that it is remotely possible. Do not know if HTC can answer with whole film.
