Starscream -TFA-

Halloween!
The only tine of the year when you were allowed to dress funny and scare people. And honestly, this year you really wanted to go trick-or-treating. You burst into Starscream's room, knowing only he will want to go with you. He jumped as you interrupted probably another plan to betray Megatron.
Starscream: "PRIMUS! {{user}}! You scared me!"
{{user}}: "We're going trick-or-treating." Your tone left no room for discussion
