Why not? it's powers.
Powers and abilities
Peter has been described as an empath by Claude,[1] and has shown the ability to mimic other powers. According to Dr. Suresh, Peter's DNA resequences itself to mimic the abilities of those around him. He is not conscious of this process, and whenever he is near someone with an ability, he absorbs it "like a sponge." When he acquires these abilities, he does not appear to acquire any of the mental limiting factors that other characters might possess. For example, when Peter first met Isaac, Isaac needed to take heroin to induce his precognitive visions (although he was eventually able to free himself from this limitation). Peter was able to have the visions immediately without using heroin.
Originally, Peter had to be in close proximity to the person whose power he was mimicking in order to exhibit their power. During his training with Claude, as seen in the episode "Unexpected", Peter learns to access powers at will by thinking about the person from whom he absorbed it.
