Andrew volunteers as Sophie's tutor when Callum passes on she needs help with geometry, but has to admit his maths talent is limited to arithmetics and accounting and suggests Summer would do better, which turns out wrong. Tash helps the kids, hoping not be found out, but when Anderw does he isn't turned off by her 'nerd talent', even brags to his mates about his smart girl, so now she starts priding herself on the Mathletes. Susan is now physically stalker-paranoid, accusing student Gemma, until savior Zeke takes her home, where she feels guilty of wimping out. Karl finds her hiding, possibly with an MS relapse.
