SPOILER

I too believe this is at the end of SG 0 when Okabe use the (recently finished) C204 time machine in 2025 to rescue Mayuri since she got lost in time during Operation Aquila / Arc Light. Not much is known of this part...my guess is that they reserve it for the OVA or for a third Steins Gate completely (that would be great).
