What's bugging me is.

Spoiler: 

Nine years before Emergence Day, Elain died in an unknown manner while in the Hollow under Jacinto doing field research in off-limts areas. Adam lied to Marcus and others about what happened, only telling them that she had gone missing. Elain's body was discovered in the Hollow while she was searching for Imulsion crystals, which they hoped to use as targeting lasers. Marcus would later know the truth about her disappearance.

Well where on earth did we find out the truth? This semi-confirms Marcus's mother is not in fact the Queen but in my opinion the Bold part once again raises more questions

Confirmation - Myrrah is "Ruth" from one of the collectibles at New Hope in Gears 2.
