Arrow 610 Divided Synopsis and Questions

      According to the synopsis for Divided,  Oliver learns some information about Cayden  James and then turns to an unlikely source for help. Two questions then emerge:  What does he  find  out? To whom does he turn? 

Oliver could  find out who  Cayden  James son  is, but that doesn't seem like a reason  for him to turn to  unlikely help, does it?  My guess is that he finds out that James has a team assembled of  BS, Vincent Sobel, Anatoly and Ricardo Diaz, aka Dragon.  So to whom could he turn?  Could  he go back to his team  and ask  them?  He could but then that does't seem so unlikely does it?  If this little synopsis  wasn't a tease then perhaps Oliver goes to Nyssa  for help.  That certainly seems like an unlikely source for help, doesn't it?

           What if Oliver gets Lance to talk with Laurel and he works with the Black Siren  for help?  Now that really would be an unlikely source, but possible if, as the writers stated, they will rehabilitate Laurel Lance.  What do you think of that possibility?  He would certainly have eyes on James, but can he really trust Laurel?  I would think Felicity would have a problem with that one.  And would it make sense to trust Laurel and not his own team?  All Rene did was chose  his daughter over the team, and  we all know if  push came to shove Oliver would make the same choice.  I don't see this a likely possibility,  do you?

Another idea  is that Oliver knows that Cayden  has eyes  on him in the bunker and he and  his team pretend  to be divided.  Whatever the reality  is, we know that the team probably won't be divided for long.
