ANOTHER SLUGTERRA THEORIES! (*Idk if you guys agree but let me know)*
•Remember in Slugterra: Into The Shadow? Tad uses the same tunnel Eli used In "The World Beneath Our Feet".
I was wondering "How'd Tad know about the tunnel"? When it's a Shane's Secret? Maybe Dr Blakk told him about the tunnel? (*That doesn't make sense, I don't think these two ever met but if they met, Blakk WOULD tell him about the tunnel*).
•Then Eli reveals that his Mom left him when he was ten. (*before or after Dr Blakk sends Will to the Deep Dark Cavern*)
Here's my theories, what if Eli's Mom leave Will and Eli bcuz she already in a relationship with Dr Blakk? And she would tell Tad about the tunnel since she's knows some of The Shane's Secrets (*Or maybe she secretly working for Dr Blakk to give him more info about The Shane's Secret?*) Bcuz In the episode "Back to Blakk" He tells Eli about the "Burning World" Or the Surface, we don't know how but we also know that NOT ALL The Shane's are good.
•So what if Eli's Mom left Eli and Will bcuz of that? Bcuz we never knew the purpose of why she left.
But yeah, let me know what you guys think!
