Log entries

Personal log, stardate 1051.8
We're in the process of abandoning our ship in order to destroy it. This is actually happening, yet somehow I still can't believe it. Long-range sensors show Control is on the move and gaining quickly. Its infiltrated our subspace radio relays, so we can't reach Starfleet for backup. Ship-to-ship communication is all we've got. Discovery contains the one thing in all the galaxy that Control needs, the data to become fully conscious. My mother sacrificed everything to stop Control from getting that data, and now she's counting on us to finish the job. But is this really the only solution? I look in the mirror and can hardly recognize myself anymore. All these questions without answers. There are seven signals, but we've only seen four. We have a time crystal that we don't know how to use. Captain Pike has always had faith that they play a part in some grand design. Now… more than ever… I wish I had his certainty.}}
Personal log, stardate 1201.7
124 days have passed since your disappearance. It has been difficult, but we've managed not to reveal the truth of Discovery's fate to Starfleet. To have done so was to have risked rendering your sacrifice meaningless. If we learned anything, we learned we're not yet ready to learn everything. Mother and Father are diplomatically immune from interrogation, and they fully understand our silence is meant to keep you safe. We have sworn never to speak your name in the presence of others. Yet I feel you with me, always. With every moment, I grow more sure-footed in this... in-between place, more certain of who I am becoming. You teach me, sister, even now. Every night, I look to the stars for your signal, and every night, I have to remind myself of the scientific truth that time is relative.
