To anyone who may have noticed, a manhole popped open in the middle of Konoha's streets. An invisible snake slithered down through the hole into the sewers of the village. Once Heihachi presented himself in the sewers, Seijuro would make visible again. He peered around curiously at the walls of the dank tunnel until his eyes found Heihachi. He stared at the old man's grisly physique and into his aging eyes. There was no beating around the bush anymore. 

"Why I have brought you here... you are a well known rebel, Senju." Seijuro began. He started to pace back and forth from wall to wall of the tunnel, his eyes never leaving Heihachi. "Fool you once, shame on me, fool me twice, shame on [i]you, Senju[/i]." Seijuro stopped and smirked for a moment before continuin to pace about. He turned away and gazed about the walls of the tunnel, alowing it to sink in that he could have double-crossed him not once but twice already. "But you trusted me yet again.. your curiosity is sparked. I'm done playing games and wasting your time, Kurage Sennin. I need a man of your qualifications to assist me with a project benefiting the both of us." Seijuro was carefully studying the Sage's reaction. 

"The details I can provide as of now are simple. You do not enjoy the Imperial control over the five great nations. I am not fond of them either, thus the enemy of my enemy is my friend. That being said I want us to enter a mutually beneficial pact of secrecy and silence. While the Empire is keeping a close eye on the known rebels there are those such as myself that are working in the shadows to ensure the success of certain objectives and goals, the nature of which to be disclosed to you pending your response to my invitation... which I'm sure you've gathered by now, Heihachi.. I'm asking you to partner up with a snake." A snide smirk crept across his left cheek as his narrowed eyes looked Heihachi straight in the eyes. His hand gently glided out of his sleeve, hoping the Sage would accept his offer. 

From what he had heard through the grapevine, Heihachi was truly still a marvel even in the waning moments of his life. He had also made a name for himself and had connections within the rebels. While not directly affiliated with the rebellion himself seeing as those involved didn't take kindly to snakes, Seijuro kept his agenda private and left his offer vague for obvious reasons. True Shinobi didn't go spilling the beans and laying all their cards on the table at once. There was certainly a reason for Seijuro's shady games for in a dog eat dog world precautions are necessary.
