- "I'd like to thank you all for coming to this very special occasion: the dedication of our beautiful new school. My grandfather spent his life laying down the foundation for our education system."
- ―Matthew Wallace[src]
He was the grandson of Eli Wallace and Cpl. Barnes. He became principal at Eli Wallace Elementary School and at the opening of the school, he made a public speech about the school and that his grandfather laid the foundation for their education and he wanted his grandfather's legacy to live on.
He then presented the last survivor of the Destiny expedition, Camile Wray, who had been mayor since the inauguration, as an honored guest. He was named after Lt. Matthew Scott. He later married and had children. (SGU: "Epilogue")
In 2010, after encountering Novus, the main timeline version of Eli Wallace watched the recording of his alternate self's grandson dedicating the school, downloaded from the Tenaran databank, before being interrupted by Dr. Nicholas Rush. Eli is revealed to have watched the recording several times and tells Rush that he intends to add it to his documentary, intrigued by what their descendants have accomplished. (SGU: "Blockade")
