Ali was talking to Toby or an A-Team Member??
Thanks to this fabulous Anonymous clue about the 3.14 and 5..05 connection (thank you so much!) I was able to find out the mystery person that Alison was talking to in the first 5 minutes of the 100th episode. Toby is seen driving a black Suburban in 3.14 and the car that Ali is seen at is the same vehicle he drove in 3.14, exact rims.
If not Toby, then a member from the A-Team being that vehicle belongs to the A-Team.
