What Episodes of 'Avengers Assemble' are these LEGO Sets Based On?

In 2014 and 2016, LEGO released sets based on the Marvel TV series 'Avengers Assemble', but what episodes are the sets based on?

While LEGO produced four sets for the series, only three of them seem to actually happen somewhat in the series' first two seasons. Unfortunately, I haven't watched the series, but luckily we have Disney+ to fast forward each episode (sorry).

Like many other LEGO license sets produced alongside upcoming projects, the sets might miss or feature more than they should. This is due to The LEGO Group (in fact, every merchandise manufacture) receiving early concept art and where they have to make the most out of it. Sometimes it appears to be correct, other times, yeah, you know. 

In 2014, LEGO produced the two sets, 76017 and 76018. While 76017 doesn't seem to appear in any scenes of the first seasons, 76018 could easily be based on the two-part story, 'The Avengers Protocol'.

In 2016, LEGO released yet another two sets, 76048 and 76049. The first set appears to be based on the Season 1 episode 'In Deep', with the latter seeming to be based on the Season 2 episode 'Thanos Rising'.

Like I said earlier, some sets might feature some things that shouldn't be there, like Iron Man's and Captain America's suits. Also, Captain Marvel doesn't appear until Season 3, and Thanos is only appearing in Season 1 and Season 2. Anyway, every figure produced for these sets are exclusive to their respective sets, so what's not to like?
