Episode 1
Okabe remembers everything that happened perfectly.

He challenged Maebara Keiichi to steal a package from two weird guys and had to defend it, and did so as he greatly trusts Keiichi.

Sadly, it didn't contain anything of interest.

Episode 2
He is in the reunion with the Bystery Busters and asks some questions, but they go unanswered.

Later on, he is tested by The Soul Brothers as reciprocation for recruiting "K" to the LabMem. By asking him to become "Cloud", to become "Tommy", "Iri" and "K", he would be a true Soul Brother! He understands instantly, and takes on to take pictures of the girl's locker room. Thus, "Okarin" aces it, and The Four Dark Heavenly Kings are now five. However, he doubts himself making any progress, and debates if he should tell them "it".
