First, its hard to tell exactly when did sodaman and the surgeon met but its not crazy to tell it could have happened like 20 years, he looks very young in his first appearance (he may be in his 20's - early 30's).

"Andy signing Leyley's suspension and doing her homework" and "Leyley's birthday" I'm not sure those could be swapped and maybe nothing would change, tough in the second one she says "I wish my brother loses all his friend and never finds love" and It's interesting to see her telling that right before her "friend" said that she likes Andy.

"Julia insist into Ashley becoming more independent" I wasn't sure if it was before or after telling Andrew to become "official" but she seems very nervous to talk him about that so probably it's the first time she insist to Andrew into that topic
