Has anyone researched the significance (or lack of) John and Tony Podesta discussing Jacob Studley and Julien Studley?

If taken literally, the sequence is:

1. "Julien Studley is very sick" and they discuss trying to help someone contact Jacob Studley. https://wikileaks.org/podesta-emails/emailid/56699

2. In reply, John asks where is Jacob? https://wikileaks.org/podesta-emails/emailid/27373

3. to which Tony has two replies: (a) was in Beijing, then Pakistan, totally undercover https://wikileaks.org/podesta-emails/emailid/32338, (b) then says "Agency I" https://wikileaks.org/podesta-emails/emailid/44261

Some simple internet research reveals Jacob is probably Julien's son, which explains why they would want to contact him if his dad is very sick. https://en.wikipedia.org/wiki/Julien_J._Studley

The open questions I have are:

• what is the Podesta brothers relationship to Jacob and Julien Studley?

• what agency are they referring to when mentioning Agency I?

It seems clear whatever agency Jacob is associated with that has him undercover around the globe (hmmm..) is also an agency that both Tony and John have a close relationship with.

Anyhow, it seemed important to document this since I could not find any mentions in this sub-verse
