On the death of Gaston in 1131, Talesa took up the regency for her young son Centule VI. Centule died in the Battle of Fraga in 1134 and the viscounty passed to the son, Peter II, of Guiscarda, Talesa and Gaston's eldest daughter. Peter II being a mere boy, Talesa continued in the regency for him until at least 1136.
