Lukas and Oak spent the rest of the day experimenting with their Frequencies. While it began with testing how Oak's Frequency reacted to certain scenarios and uses, it eventually morphed into general experimentation with both of their Frequencies.
For Lukas, Oak had plenty of ideas for Lukas to test, only for most of them to be shot down for either being impossible, irresponsible, or something Lukas had already tried to do before. There was also no way for their Frequencies to be compatible with each other in such a way as for them to test both at the same time. Oak's Frequency dealt with physical objects, while Lukas' was completely metaphysical in nature, dealing with a concept rather than something physical.
