Eyes on Kazuhira

One of the more cryptic statements of the slow-talking Navajo, Code talker states this in any mission in the middle arc, confirmed to be anywhere between mission 32 and 46. These messages are clearly intended for the player, as The parasites cannot learn to speak Navajo and Venom Snake is only fluent in English.
 * The number one leg joint is loose. (???)
 * Hmph, Borscht again today. (???)
 * Borscht is a dish popular in Russia, so it's probably Ocelot eating it.
 * Secret meetings between the containers, in broad daylight?
 * Likely a reference to Mission 35. Code talker contacts you while you're between containers to give you tips on jungle sneaking. Needs further investigation.
 * In Japanese, the word 逢瀬 is used for the "secret meeting between containers". This word specifically means "secret meeting between a man and a woman in love".
 * The Ocelot's aim is off today (???)
 * Eyes on Kazuhira. A message from the parasites.
 * There are many theories about this, especially considering Kazuhira's apparent photophobia - sensitivity to light.
 * In Japanese, this line reads: 一番脚のジョイントが緩んどる ふん　今日のメインはボルシチか コンテナの隙間で昼間っから逢瀬とはな 山猫は調子が出ないようだ カズヒラに気を許すな 虫の知らせだよThe "eyes on Kazuhira" line translates to something closer to "Be on your guard against him." with no mention of his eyes.
