"It was originally speculated that the Stalker could be a Tenno, however it is unknown if its true.

+ During The Second Dream Quest, the Lotus says that the "truth" of the Tenno Reservoir "drove the Stalker to madness"."

The context of the Lotus's statement is missing here. She explains that this is among the reasons that she didn't tell "you" about the Dream.

This heavily implies that the Stalker is a Tenno that went mad when they learned about the Dream, which is why the Lotus hid it from the other Tenno to prevent similar outcomes.
