The Cryogenics Pods seem like a big ol' Chekov's Gun on both the SSV Normandy and the Normandy SR-2. However, I did not see them being used in any of the Trilogy games nor did I notice any entries in the Codex.
In fact, there's little to no mention of them even in the Mass Effect Wiki - they're not at all noted in the SSV Normandy article, and only called out as a reference point for getting to the Main Battery in the Normandy SR-2 article.
Were they just there to add fluff, or is there some actual use for or history behind them?
