[Phone Call to Myrcella Baratheon - This Afternoon]
After the altercation with Caroline and Klaus, Jeremy had rushed off, leaving the stake on the ground where it had landed and rushed to find a place where he could call Myrcella. In the dreams he might have called Matt or Ric, but Matt hadn't started dreaming yet and Ric wasn't around, so the most logical person was his girlfriend.
Reaching his car, in the parking lot, Jeremy got in, his phone already in his hand and his finger pressing Myrcella's number.
