Thanks for checking in with the responders! We always love to these questions to come full circle.
You mention your concern regarding homes that your current agent showed you (thanks for clarifying that the relationship is "implied" by the way). IF you end up moving forward on a home that agent #1 showed you...and he or she finds out...he or she may seek compensation. He or she may not be able to prove that he/she had "procuring cause" but just be aware that it could come up sometime down the line.
Keep us posted!
