Older Wyatt (Wes Ramsey) should not have powers. In S01E17, when the Halliwells traveled to the 1970s, only their little counterparts had powers.
When Paige orbs in from New Zealand, holding a mask over her face, the mask is implied to be from Maori people, but is completely foreign to the culture with no features from Maori or even Polynesian art.
Future Wyatt doesn't believe that Vicus is a demon when he first sees him in his bedroom, even though he witnesses him using demonic powers (shimmering and voyeurism), which any witch could identify as demonic.
