Steam

With Sebastian’s radar-like intuition for saunas, it’s not too surprising that some of Tyson’s better memory are there.

However, that does not explain how danger unaware the normally super cautious Tyson becomes around steam.

Everything else Tyson treats with healthy distrust and he understands objectively that steam can be dangerous, but his immediate impulse around steam is to put his face in it and be warm; be this steam from the shower, kettle, or convoluted enemy trap.

He has burnt his hands a frankly embarrassing number of times by waving them above a boiling kettle simply because its warm.

Archery

Though archery was also one of the many lessons that Tyson and Jethro were given as heirs to the Delaney family legacy, the brothers are far more likely to remember playing with Nerf-dart bows than the actual archery lessons.

Archery was one of the few activities where their father would actually watch them whilst they practiced. Perhaps simply as those lessons lined up with warmer, fairer weather that coaxed the Professor outside, but it meant that they looked forward to them; and practiced with the toy bows to impress him.
