DO NOT GO

This is not an option. This is almost an ethical breach. That L should know better than allow any contact with oposition during proceedings. It could confuse you. It could compromise you. Or were he to drink too much and talk to openly it could do the same for his client. It is not an option.

Please do what Tom suggested and share the story with your L, if for no other reason than to make sure it does not come back on you later ... told in quite the opposite story line.
