Here are some predictions I have how they will tie HIMYF back to HIMYM.

• Sophie or Valentina will end up on a date with Barney

• Charlie will get a job at GNB, in Ted's Building

• Robin will make a appearance on their TV, possibly with them playing the "But Um" game

• Ranjit will be their driver at some point.

•Jesse will get into legal trouble and Marshal will be the judge.

• Ellen will randomly meet Lily and discuss an issue she is having with her, to which she will suggest some version of "Aldren Justice"

This is all I have so far, let me know what you all think and add more if you have any predictions yourself.
