In Dr. Wells opening speech, his hands are clasped before him, but when the camera changes, his hands are on the plastic podium.

When Iris first sees Wells in the lab he is standing with his hands on his waist but immediately afterwards his arms are folded.

When talking about Dr. Light's powers, the alternate Dr. Wells states that, since she can harness power from starlight, she can generate beams of energy with the same temperature as a typical star, 5,300 Kelvins. That's only the surface temperature of a typical star. Our sun's surface temperature is around 5,700 Kelvins (5,426 °C or 9,800 °F); however, the temperature at the core where nuclear fusion of elements occur (mostly hydrogen and helium) is estimated to be as high as 15,000,000 Kelvins (14,999,727 °C or 26,999,540 °F); so, while she may not be able to generate the same amount of heat as the sun's core, she'd be able to generate much more then 5,300 Kelvins. Plus, the photons from the energy beams she generates would be so energetic that anyone within even an indirect line of light of her would have their retinas burned out and be blinded forever. In fact, at close range to something as luminescent as the sun, you'd need several inches of solid lead or titanium to block the sun's highly energetic photons. In other words, the materials of most buildings (wood, plaster, dry wall, etc.) would not be able to block the light coming from her beams; people outside the building for miles around would be blinded, too.

As soon as Joe sees Harrison Wells, he draws his gun and fires. As Wells is unarmed and poses no obvious threat, no trained police officer (like Joe) would have done this. However, Joe believes the man he's shooting at is Reverse Flash.
