I would imagine this to be her letter to his parents once they came into contact with the Federation
Dear Mr. and Mrs. Kim,
I wished to contact you to tell you how marvelously and exemplary your son has been fulfilling his obligations as Head of Operations. Of course -- no one is perfect, he was almost on the point of mutiny for a few times, but on the whole he went above and beyond his responsibilities.
There have been some minor trifles and hiccups on the way you perhaps should know about, though - he got replaced by an other-dimensional duplicate, the original version being sucked into the vacuum of space screaming for help, he was eaten alive one cell at a time by a species 8472 infection without us even being able to sedate him, he was tortured in an alien prison camp more than once, infected by a few alien diseases, altering his genetic code, making him glow, or having viruses that eventually grew to the size of multispectral deep space probes escape from his orifices, he might have died and be resurrected, oh I believe, three, four times, a few run ins with the Borg with the Borg Queen personally telling him she would see him later, and other species hunting on us for our organs or flesh, but nothing too strenuous or outrageous, I assure you. However, should he start acting up weirdly at some point, the cause might be found somewhere between those - telling you just in case. We have often seen people are not quite as sound psychologically as they should be and are still complaining about such things two weeks later.
Should he ever need a glowing letter of recommendation for his next post, you can always write me for that, I would be most pleased to provide that for him. Even though I do think he is not quite ready for promotion yet. Yes, he has commanded the bridge at times, and also has been captain of an alien vessel, but on the whole, I think that before I can recommend that promotion to Lt. Jg., he would need at least a full year of full time experience commanding a fleet of at least 20 ships. I have such high expectations of him that I can't start lowering my bar now. For Tom Paris, for example, that bar would be much lower; not commiting crimes for some period of time would be sufficient to earn him that promotion. Some may call it unfair; I call it "personalized profile policy" trying to give everyone maximum incentive to stretch for more.
This way, I feel I'm doing the best for his future potential.
Yours faithfully,
capt. Kathryn Janeway.
